# Reflex Angle-Real-life Example of Reflex Angle

When two rays or line segments meet at a common endpoint, we call that a vertex, and the angle between them is measured in degrees. A full rotation is 360 degrees. The word “angle” comes from the Latin word “angelus,” which means “corner.” There are different types of angles that can be formed on a plane surface, including acute angle, obtuse angle, right angle, reflex, and straight.

In this article, we’re focusing on one particular type of angle: the Reflex Angle. We’ll discuss its definition and examples in detail so you can get a better understanding of what it is and how it works.

## What is a Reflex Angle?

A reflex angle is any angle that measures greater than 180 degrees and less than 360 degrees. A reflex angle and the angle that lies on the other side of it form a complete angle of 360°. The following figure provides an example of what a reflex angle looks like.

## Degree

181°, 190°, 200°, 210°, 220°, 230°, 240°, 250°, 260°, 270°, 280°, 290°, 300°, 310°, 320°, 330°, 340°, 350°, and 359° are all reflex angles according to the definition of a reflex angle. A reflex angle is any degree that lies between a straight angle (180 degrees) and a full rotation (360 degrees).

## Reflex Angle Triangle

A reflex angle is an angle that is greater than 180 degrees, and the sum of all of the internal angles in a triangle is equal to 180 degrees. This means that it is not possible to draw a reflex angle triangle.

## Reflex Angle Diagram

In the figure below, the angle is a reflex angle that lies between 180° and 360°.

## Real-life Example of Reflex Angle

There are many reflex angles that we can observe in our daily lives. Here are a few examples:

• When we fold our arms, the angle created at the elbow is a reflex angle.
• The hands of a clock form a reflex angle at 7’O clock, 8’O clock, and so on when we measure in the clockwise direction.
• When you open a book and the pages form a reflex angle.

## How to Measure a Reflex Angle

There are two ways to measure a reflex angle:

By measuring the interior angle and subtracting it from 360 degrees.

By using a protractor to measure the reflex angles itself.
