Angles: Complementary, Supplementary, and Vertical

This video tutorial covers the identification and calculation of unknown angle measures. It introduces key vocabulary such as adjacent, complementary, supplementary, and vertical angles. The tutorial provides examples and practice problems to help students understand how to find unknown angles using these concepts. Advanced problems are also included to challenge students' understanding and application of angle calculations.

What is the definition of adjacent angles?

• Angles that are opposite each other

• Angles that add up to 180 degrees

• Angles that add up to 90 degrees

• Angles that share a common side and vertex

How can you remember the difference between complementary and supplementary angles?

• Complementary angles are larger than supplementary angles

• Complementary angles add up to 180 degrees, while supplementary add up to 90 degrees

• Complementary angles add up to 90 degrees, while supplementary add up to 180 degrees

• Complementary angles are always equal

What is a characteristic of vertical angles?

• They form a straight line

• They are adjacent to each other
