An angle whose measure is equal to a full revolution is a complete angle.

A complete angle is a type of angle that measures 360 degrees or the equivalent of one full revolution. It is formed when two rays or line segments diverge from a common point, called the vertex, and sweep around in a circular motion to form a complete circle.

Explanation:

1. Angle Measurement:
Angles are measured in degrees, which is a unit of measurement for angles. A full revolution or a complete circle is divided into 360 equal parts, each representing one degree. Therefore, an angle that measures 360 degrees completes a full revolution.

2. Definition of a Complete Angle:
A complete angle is defined as an angle that measures 360 degrees or the equivalent of one full revolution. It is represented by a small circle drawn at the vertex of the angle to indicate its completeness.

3. Angle Types:
There are various types of angles based on their measures:
- Right Angle: A right angle measures exactly 90 degrees.
- Obtuse Angle: An obtuse angle measures more than 90 degrees but less than 180 degrees.
- Straight Angle: A straight angle measures exactly 180 degrees.
- Complete Angle: A complete angle measures exactly 360 degrees.

4. Characteristics of a Complete Angle:
A complete angle has the following characteristics:
- It forms a full revolution or a complete circle.
- The rays or line segments forming the angle sweep around in a circular motion.
- The measure of a complete angle is equal to 360 degrees.
- It is represented by a small circle at the vertex.

Conclusion:
In conclusion, an angle whose measure is equal to a full revolution is called a complete angle. It measures 360 degrees or the equivalent of one full revolution. This type of angle forms a complete circle and is represented by a small circle at the vertex.
