An angle is formed by two rays connected to a common vertex

Types of Angles

The different types of angles based on their measurements are:
  • Acute Angle – An angle less than 90 degrees.
  • Right Angle – An angle that is exactly 90 degrees.
  • Obtuse Angle – An angle more than 90 degrees and less than 180 degrees.
  • Straight Angle – An angle that is exactly 180 degrees.
  • Reflex Angle – An angle more than 180 degrees and less than 360 degrees.
  • Full Angle – An angle that is exactly 360 degrees.

How Angles Are Measured

Angles are measured in degrees ( °), using a protractor or using indirect measurement with the assistance of Angle Theory.
