Understanding Vertical Angles

The video tutorial explains vertical angles, which are angles opposite each other when two lines intersect. It demonstrates that vertical angles are congruent, meaning they have equal measures. The tutorial provides an example with specific angle measurements to illustrate how to calculate vertical angles and discusses the relationship between adjacent angles, which are supplementary and add up to 180 degrees.

What are vertical angles?

• Angles that are across from each other

• Angles that are adjacent to each other

• Angles that are complementary

• Angles that are supplementary
