Geometry

How to solve

An angle is the amount of turn between two rays that share a vertex. Diagrams mark that region; your job is to report the measure in degrees.

Steps

  1. Identify the vertex (where the rays meet).
  2. Look at the marked wedge — that is the angle being asked.
  3. Enter the measure in degrees (no degree symbol needed).

Example

Two rays meet at O with a marked right angle.

  1. A right angle measures 90°.

Answer: 90
