Question

which angles are vertical to each other? ∠1 and ∠3 ∠5 and ∠11 ∠12 and ∠3 ∠15 and ∠4 submit work it out not feeling ready yet? these can help: angle vocabulary (100) lesson: complementary angles lesson: supplementary angles lesson: vertical angles lesson: adjacent angles

Explanation:

Step1: Recall vertical - angles definition

Vertical angles are formed when two lines intersect. They are opposite each other and are congruent.

Step2: Analyze each option

• For ∠1 and ∠3: They are adjacent angles formed by two intersecting lines, not vertical angles.
• For ∠5 and ∠11: When we consider the intersection of lines, ∠5 and ∠11 are vertical angles as they are opposite each other at the intersection.
• For ∠12 and ∠3: They are not related as vertical - angles.
• For ∠15 and ∠4: They are not vertical angles.

Answer:

∠5 and ∠11
