Tutorial

- Angle - An angle is a figure formed by two lines that intersect at a point.

- Right Angle - An angle that has an angle measure of 90º.

- Angle Congruence - Angle congruence means that two angles have the same angle measure in degrees.

- Supplementary Angles - Two angles are supplementary if their sum adds up to 180º.

- Complementary Angles - Two angles are complementary if their sum adds up to 90º.

- Adjacent Angles - Adjacent angles are angles that share a leg.

- Linear Pair of Angles - A linear pair of angles is a set of angles that are adjacent and supplementary.

- Vertical Angles - Vertical angles are formed from two intersecting lines and are opposite one another. They are congruent.
