Properties and Relationships of Angles

This video tutorial covers angle relationships, including congruent, complementary, and supplementary angles. It explains how to use a protractor to measure angles and solve equations involving angle measures. The tutorial also discusses identifying vertical and adjacent angles and solving two-step equations related to angles.

• They are adjacent

• They form a straight line

Adjacent angles share which of the following?

• A vertex and a side

• A vertex and a line

• A line and a point

• A side and a line

What do supplementary angles add up to?

• 360 degrees

• 180 degrees

• 270 degrees

• 90 degrees

Which of the following is a property of vertical angles?

• They are always congruent

• They are always supplementary

• They are always complementary

• They are always adjacent

If two angles are adjacent and form a straight line, what are they called?

• Vertical

• Supplementary
