Key Facts

Complete Angle = 360 degrees.

Shape: Forms a full circle.

Relation: 1 Complete Angle = 2 Straight Angles (180 + 180) = 4 Right Angles (90 × 4).

Definition

A Complete Angle is an angle whose measure is exactly 360 degrees (360°).

Imagine the minute hand of a clock. Starting from 12, when it completes one full round and comes back to 12, it has swept through a complete angle of 360°.

Types of Angles Review

  1. Acute Angle: Less than 90°.
  2. Right Angle: Exactly 90°.
  3. Obtuse Angle: Greater than 90° but less than 180°.
  4. Straight Angle: Exactly 180° (a straight line).
  5. Reflex Angle: Greater than 180° but less than 360°.
  6. Complete Angle: Exactly 360°.
