REFLEX ANGLE

Reflex Angle

Definition Of Reflex Angle

Reflex Angle is an angle that lies between 180° and 360°.

More About Reflex Angle

A full angle is also a reflex angle.

Example of Reflex Angle

Example of Reflex Angle

The angle is a reflex angle as the angle is more than 180° and less than 360°.

Video Examples: Reflex Angle

Solved Example on Reflex Angle

Ques: Which among the following represents a reflex angle?

Solved Example on Reflex Angle

Choices:

A. Figure 1
B. Figure 2
C. Figure 3
D. Figure 4
Correct Answer: C

Solution:

Step 1: Reflex Angle is an angle that lies between 180° and 360°
Step 2: Here, the angle in Figure 3 is more than 180° and less than 360°
Step 3: So, the angle in Figure 3 is a reflex angle.

Quick Summary

  • Reflex angles are larger than straight angles (180°).
  • Reflex angles are smaller than a full rotation (360°).

Q2: An angle measures 200°. Is it a reflex angle?

Frequently Asked Questions

Q: What is the difference between a reflex angle and an obtuse angle?
A: An obtuse angle is greater than 90° and less than 180°, while a reflex angle is greater than 180° and less than 360°.

Q: Can a reflex angle be equal to 360°?
A: No, a reflex angle is strictly less than 360°. A 360° angle is a full angle, not a reflex angle.
