An angle is a measurement which shows how far something has rotated.

types of angle :

  • acute less that 90°
  • right angle 90°
  • obtuse more than 90° but less than 180°
  • straight line 180°
  • reflex more than 180° but less than 360°
  • full turn 360°


Here are some angle facts that can help you:

  1. Angles of a triangle always add up to  180
  2. Angles on a straight line always add up to 180
  3. Angles on a point always add up to 360

In a test these may be the reasons why some angles are not labeled.
