Vertical and Adjacent Angles Concepts

This lesson focuses on solving for unknown angles using equations. It covers several examples, including solving for angles T, V, X, AOB, and BOC by applying concepts of vertical and adjacent angles. Each example involves setting up and solving equations to find the unknown angles, reinforcing the understanding of angle relationships and equation solving techniques.

What is the sum of vertical angles?

• They sum up to 90 degrees.

• They sum up to 180 degrees.

• They are always equal.

• They are complementary.

If two angles are vertical and one is 26 degrees, what is the measure of the other angle?

• 116 degrees

• 90 degrees

• 26 degrees

• 64 degrees

What is the relationship between two adjacent angles that form a right angle?

• They are equal.

• They are vertical.
