Mastering Adding and Subtracting Rational Expressions

This video tutorial covers basic angle relationships, including vertical, adjacent, complementary, and supplementary angles. It provides definitions, properties, and examples for each type of angle, along with practice problems to reinforce understanding. The tutorial concludes with word problems and a humorous note on measuring angles.

What defines vertical angles?

• Angles that are next to each other

• Angles that sum up to 90 degrees

• Angles that sum up to 180 degrees

• Angles across from each other when two lines intersect

If two angles are vertical angles, what can be said about their measures?

• They are complementary

• They are congruent

• They are supplementary

• They are adjacent

What is true about adjacent angles?

• They are across from each other when two lines intersect

• They always sum up to 180 degrees

• They are always congruent

• They share a common vertex and a common side

How can adjacent angles be identified?

• By their common side and vertex

• By their sum of 90 degrees

• By their opposite positions

• By their equal measures

What is the sum of complementary angles?

• 45 degrees

• 90 degrees

• 360 degrees

• 180 degrees

What is the sum of supplementary angles?

• 90 degrees

• 45 degrees

• 180 degrees

• 360 degrees

In a pair of complementary angles, if one angle measures 30 degrees, what is the measure of the other angle?

• 90 degrees

• 60 degrees

• 30 degrees

• 150 degrees

What relationship do angles forming a straight line have?

• Congruent

• Adjacent

• Supplementary

• Complementary

If angle X is 107 degrees and is a vertical angle with angle Y, what is the measure of angle Y?

• 53 degrees

• 180 degrees

• 107 degrees

• 73 degrees

When solving for angle G in a supplementary pair where angle H is 51 degrees, what is the measure of angle G?

• 129 degrees

• 51 degrees

• 231 degrees

• 180 degrees
