FAQs
What is a Reflex Angle?
A reflex angle is an angle that measures more than 180 degrees and less than 360 degrees. It is the larger angle when you go around a point from one side of a line to the other.
How do you differentiate between a Reflex Angle and an Obtuse Angle?
An obtuse angle measures more than 90 degrees but less than 180 degrees, whereas a reflex angle measures more than 180 degrees but less than 360 degrees.
Can a Reflex Angle be negative?
No, angles are defined to be positive. Reflex angles measure between 180 and 360 degrees, which are positive values.
Why is it important to calculate Reflex Angles?
Calculating reflex angles is crucial in various fields like engineering, architecture, and mathematics, as it helps in understanding the geometrical properties and relationships between different shapes and forms.
