Exploring Adjacent and Vertical Angles

The video tutorial covers the concepts of adjacent and vertical angles, explaining their definitions and properties. It provides examples of each type of angle, demonstrates how to name angles using vertices and side points, and guides viewers through identifying and solving problems involving these angles. The tutorial also includes instructions for drawing vertical angles using a protractor.

What are adjacent angles?

• Angles that are opposite each other

• Angles that add up to 90 degrees

• Angles that share a common side and vertex

• Angles that form a straight line

What is true about vertical angles?

• They share a common side

• They form a straight line

• They are always 90 degrees

• They are congruent

Which of the following is a correct way to name an angle?

• Using only the vertex

• Using the vertex and two side points

• Using only one side point

• Using any three points
