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
