Question

Accepted Answer

### 1.
# Brief Explanations:
The notation $\overleftrightarrow{AB}$ represents a line that extends infinitely in both directions through points $A$ and $B$, so it matches "Line $AB$".
# Answer:
H. Line AB

### 2.
# Brief Explanations:
The notation $\overrightarrow{AB}$ has a starting point at $A$ and extends infinitely in the direction of $B$, which is the definition of a ray, so it matches "Ray $AB$".
# Answer:
E. Ray AB

### 3.
# Brief Explanations:
The notation $\overline{AB}$ represents a line segment with endpoints $A$ and $B$, so it matches "Line segment $AB$".
# Answer:
C. Line segment AB

### 4.
# Brief Explanations:
The notation $\overarc{AB}$ (written as $\stackrel{\frown}{AB}$ here) represents the arc between points $A$ and $B$ on a circle, so it matches "Arc $AB$".
# Answer:
M. Arc AB

### 5.
# Brief Explanations:
The notation $AB$ (without any arrows or overlines) is typically used to represent the distance between points $A$ and $B$, so it matches "Distance of $AB$".
# Answer:
D. Distance of AB

### 6.
# Brief Explanations:
The notation $\odot A$ is the standard symbol for a circle with center $A$, so it matches "Circle $A$".
# Answer:
B. Circle A

### 7.
# Brief Explanations:
The notation $\angle A$ is used to denote an angle with vertex at $A$, so it matches "Angle $A$".
# Answer:
G. Angle A

### 8.
# Brief Explanations:
The symbol $\cong$ is used to indicate that two geometric figures (like segments, angles, etc.) are congruent, so it matches "Congruent to".
# Answer:
F. Congruent to

### 9.
# Brief Explanations:
The symbol $
eq$ is used to show that two quantities or figures are not equal, so it matches "Not equal to".
# Answer:
A. Not equal to

### 10.
# Brief Explanations:
The symbol $\perp$ is used to indicate that two lines intersect at a right angle (90 degrees), meaning they are perpendicular, so it matches "Perpendicular lines".
# Answer:
L. Perpendicular lines

### 11.
# Brief Explanations:
The symbol $\parallel$ is used to show that two lines never intersect and are always the same distance apart, meaning they are parallel, so it matches "Parallel lines".
# Answer:
K. Parallel lines

### 12.
# Brief Explanations:
Tick marks (the small marks on segments) are used to indicate that segments are congruent (have the same length), so "tick marks" match "Congruent segments".
# Answer:
I. Congruent segments

### 13.
# Brief Explanations:
Arc marks (the marks on arcs) are used to indicate that arcs are congruent (have the same measure), so "arc marks" match "Congruent angles" (wait, actually, arc marks can also be for congruent arcs, but in the context of angle congruence, arc marks on angles indicate congruent angles. Since the option is "Congruent angles" and the other congruent - related option for segments is already used, and arc marks on angles show congruent angles, it matches "Congruent angles".
# Answer:
J. Congruent angles
