Study Notes
Introduction to Lines and Angles
- A line segment has two endpoints, while a line extends endlessly in both directions.
- A ray has one endpoint and extends infinitely in one direction.
- An angle is formed when two lines or line segments meet at a point.
- Acute angles measure less than 90 degrees.
- Obtuse angles measure more than 90 degrees but less than 180 degrees.
- Right angles measure 90 degrees.

Complementary Angles
- Two angles are complementary if the sum of their measures is 90 degrees.
- Each angle is considered the complement of the other.
Supplementary Angles
- Two angles are supplementary if the sum of their measures is 180 degrees.
- Each angle is considered the supplement of the other.
