Question

List three other situations where reflex angle may be seen.

Answer 1

Hint: Angles can be seen in many places and things around us in our day-to-day life. There are six major types of angles, one of those angles is the reflex angle. The angle between the range $${180}^{\circ }>\theta >{360}^{\circ }$$ is known as reflex angles. We are going to find some situations where the reflex angle can be seen.

Complete step-by-step solution:
We aim to find three situations where the reflex angle can be seen.
When two rays join together at a common point, an angle is formed. Let us draw a diagram for a clear idea.

Here A and B are the two rays joining at a point O then the angle formed is $$\theta$$. The point O is called a node and OA and OB are called arms of an angle.
There are six types of angles: Acute angle, obtuse angle, right angle, straight angle, reflex angle, and full rotation.
Here we are asked for a reflex angle. The reflex angle is an angle whose measure is between the range $${180}^{\circ }>\theta >{360}^{\circ }$$. The below diagrams are some of the reflex angles.

Now we are going to see some situations where the reflex angle can be seen.
The first situation is pizza, the whole pizza will be in $${360}^{\circ }$$ but when one or two pieces are taken then the pizza will resemble a reflex angle.

The second situation is Clock. The hand of the clock represents the reflex angle.

The third situation is the tip of an arrow. The arrow’s head portion resembles the reflex angle.

Thus, we have shown three situations where the reflex angle can be seen.

Note: An angle can be measured in three units: degree, gradian, and radian. The angles are mostly measured in the units called degrees and the instrument used to measure angle is a protractor. Protractors will have measurements in degree from $$0^{\circ }$$ to $${180}^{\circ }$$.
