Question

Accepted Answer

Let's solve each problem one by one (we'll go through problems 1 - 10):

### Problem 1:
# Explanation:
## Step 1: Identify given info
We have a quadrilateral with a diagonal, two sides marked equal (S), one angle marked (A), and the diagonal is reflexive (common side). But the angle is not between the equal sides.
## Step 2: Check congruence criteria
SAS requires angle between two sides. Here, the angle is not included, so the triangles aren't congruent by SAS (or other criteria here).
# Answer: Not congruent

### Problem 2:
# Explanation:
## Step 1: Identify given info
A quadrilateral (looks like a kite or rhombus - like) with a diagonal, right angles at the corners, and the diagonal is common. Let's check sides/angles. Wait, the triangles formed: do we have enough? Wait, actually, let's see: the two triangles share the diagonal, have a right angle, and maybe a side? Wait, no, maybe the markings: the angles at the corners are right angles, and the diagonal is common. Wait, but do we have two sides? Wait, maybe the quadrilateral has two adjacent sides equal? Wait, no, the diagram: the two triangles: let's check congruence. Wait, actually, maybe ASA? Wait, no, let's re - examine. Wait, the original problem: the two triangles: do they have a right angle, a common side, and another angle? Wait, maybe the answer is: Let's see, the two triangles: angle (right angle), side (diagonal), angle? Wait, no, maybe the triangles are congruent by ASA? Wait, no, maybe I made a mistake. Wait, the user's initial work says nothing, but let's solve. Wait, the quadrilateral: the two triangles: each has a right angle, the diagonal is common, and the angles adjacent to the diagonal: are they equal? Wait, maybe the triangles are congruent by ASA. Wait, no, let's check. Alternatively, maybe SAS: right angle, side (diagonal), and a side? Wait, maybe the answer is: Yes, by ASA (or SAS). Wait, no, let's do it properly. The two triangles: angle (right angle), side (diagonal), angle (the angle between the diagonal and the side). Wait, maybe the triangles are congruent by ASA. Wait, I think the correct answer is: Yes, by ASA (or SAS). Wait, no, let's re - check. The two triangles: ∠ = 90°, side (diagonal), ∠ (vertical angles? No, adjacent angles). Wait, maybe the answer is: Yes, by ASA. But maybe I'm wrong. Alternatively, maybe the triangles are congruent by SAS. Let's assume: the two triangles have a right angle, a common side, and another side equal. So, Yes, by SAS (or ASA). Wait, maybe the answer is: Yes, by ASA (or SAS). But let's proceed.
# Answer: Yes, by ASA (or SAS) (exact depends on diagram, but likely congruent)

### Problem 3:
# Explanation:
## Step 1: Identify given info
A triangle with a median (or altitude) that is a common side (reflexive), and all three sides marked equal (SSS). So, the two triangles formed by the segment (reflexive side) have three sides equal (SSS congruence).
## Step 2: Apply SSS
If three sides of one triangle are equal to three sides of another triangle, they are congruent by SSS.
# Answer: Yes, by SSS

### Problem 4:
# Explanation:
## Step 1: Identify given info
Two triangles with a vertical angle (equal), and two sides marked equal (the sides forming the vertical angle? Wait, no, the diagram: two triangles with a common vertical angle, and two sides (the ones opposite? No, the sides adjacent to the vertical angle? Wait, the markings: two sides (one on each triangle) are marked equal, and the vertical angle is equal. Wait, no, the diagram: two triangles, with a vertical angle (so equal angle), and two sides (the sides forming the vertical angle? Wait, no, the markings: the two sides (one from each triangle) are marked equal, and the vertical angle. Wait, maybe ASA? Wait, no, let's see: the two triangles: angle (vertical angle, equal), side (marked equal), angle (the other angle, marked equal? Wait, the diagram has two angles marked equal (the base angles) and one side marked equal. Wait, maybe AAS. Wait, the two triangles: ∠ = ∠ (vertical angle), ∠ = ∠ (the base angles), and side (marked equal). So, AAS. So, congruent by AAS.
# Answer: Yes, by AAS

### Problem 5:
# Explanation:
## Step 1: Identify given info
Two triangles with one side marked equal, one angle marked equal, and another side? Wait, the first triangle has a side marked, an angle, and the second triangle has a side marked, an angle. Wait, the angle is not between the sides? Wait, no, let's check: the two triangles: one has a side (marked), an angle, and the other has a side (marked), an angle. Wait, the angle is between the side and another side? Wait, no, the markings: the first triangle: side (marked), angle, side (unmarked). The second triangle: side (marked), angle, side (unmarked). Wait, maybe SAS? Wait, the angle is between the marked side and the unmarked side? If the marked sides are corresponding and the angles are corresponding, then SAS. Wait, the two triangles: side (marked) - angle - side (unmarked) for both, so SAS. So, congruent by SAS.
# Answer: Yes, by SAS

### Problem 6:
# Explanation:
## Step 1: Identify given info
Two right - angled triangles, with a vertical angle (equal), and two sides marked equal (the legs). Wait, the two triangles: right angle, vertical angle (equal), and a leg marked equal. Wait, no, the sides: the two triangles have a vertical angle (so equal angle), and two sides (the legs) marked equal. Wait, maybe ASA? Wait, no, let's see: the two triangles: right angle (90°), vertical angle (equal), and a leg (marked equal). Wait, that's AAS (angle - angle - side). Or SAS: right angle, leg (side), vertical angle? No, SAS is side - angle - side. Wait, the two triangles: they have a right angle, a vertical angle (equal), and a leg (side) equal. So, AAS. Also, since they are right - angled, we can use HL (Hypotenuse - Leg), but do we have hypotenuse? Wait, no, the legs are marked. Wait, the two triangles: let's see, the vertical angle is equal, right angle is equal, and one leg is equal. So, AAS. So, congruent by AAS (or SAS, or HL).
# Answer: Yes, by AAS (or SAS or HL)

### Problem 7:
# Explanation:
## Step 1: Identify given info
Two triangles: one has a side marked, an angle, and another side. The other has a side marked, an angle (but the angle is obtuse vs acute? Wait, no, the markings: the first triangle: side (marked), angle (acute), side (marked). The second triangle: side (marked), angle (obtuse), side (marked). Wait, the angle in the first is acute, in the second is obtuse. So, the included angles are not equal. So, the triangles are not congruent.
# Answer: Not congruent

### Problem 8:
# Explanation:
## Step 1: Identify given info
Two triangles: let's count the markings. First triangle: two sides marked (two ticks and one tick), second triangle: two sides marked (two ticks and one tick). Wait, let's list the sides: first triangle: side with two ticks, side with one tick, side with three ticks? No, wait, the first triangle: sides: two ticks, one tick, and three ticks? No, the diagram: first triangle: two sides: two ticks and one tick, second triangle: two sides: two ticks and one tick, and the third side? Wait, no, the first triangle: sides: let's say side1: two ticks, side2: one tick, side3: three ticks? No, the second triangle: side1: two ticks, side2: one tick, side3: three ticks? Wait, no, the markings: first triangle: two sides (two ticks and one tick), second triangle: two sides (two ticks and one tick), and the third side: are they equal? Wait, the first triangle: sides: two ticks, one tick, and the third side. The second triangle: sides: two ticks, one tick, and the third side. Wait, actually, the two triangles have all three corresponding sides equal (SSS). So, congruent by SSS.
# Answer: Yes, by SSS

### Problem 9:
# Explanation:
## Step 1: Identify given info
Two triangles formed by two intersecting lines (vertical angles). The sides: one triangle has a side with three ticks, a side with two ticks. The other triangle has a side with three ticks, a side with two ticks. And the vertical angle is equal. So, SAS: side (three ticks) - angle (vertical angle) - side (two ticks). So, congruent by SAS.
# Answer: Yes, by SAS

### Problem 10:
# Explanation:
## Step 1: Identify given info
A quadrilateral (looks like a parallelogram - like) with a diagonal. The two triangles: one has a side with three ticks, a side with two ticks, and the diagonal. The other has a side with three ticks, a side with two ticks, and the diagonal. So, SSS: three ticks side, two ticks side, and diagonal (common side). So, congruent by SSS.
# Answer: Yes, by SSS
