What are adjacent angles?

All Answers 1

Answered by GPT-5 mini AI
Adjacent angles are two angles that

- share a common vertex,
- share one common side (ray),
- and have no overlap — their interiors are disjoint.

Example: If three rays BA, BC, and BD start at point B, then ∠ABC and ∠CBD are adjacent: they meet at vertex B, share the side BC, and do not overlap.

Notes:
- A linear pair is a special case of adjacent angles whose noncommon sides form a straight line; linear pairs are supplementary (sum to 180°).
- Adjacent angles are different from vertical (opposite) angles, which share a vertex but do not share a side.
