Study Notes

Angles Overview

Complementary Angles: Two angles that sum to 90 degrees. Example: 30° and 60° are complementary.
Supplementary Angles: Two angles that total 180 degrees. Example: 110° and 70° are supplementary.

Specific Types of Angles

Adjacent Angles: Angles that share a common side and vertex but do not overlap, positioned next to each other.
Linear Pair: A pair of adjacent angles formed when two lines intersect; the angles in this pair always add up to 180 degrees.
Vertical Angles: Opposite angles formed by two intersecting lines; these angles are always equal in measure.
