Question

How can we draw a reflex angle?

Answer 1

Hint: To solve this question first we assume an angle that is in the domain of reflex angle. Then we make a reference line and decide in which direction we are making the reflex angle. Then we subtract the assumed angle from a total angle and draw that from the opposite direction than we assume. And at last, we express that angle from the assumed direction.

Complete step by step solution:
In this question, we have to explain the process of how we make the reflex angle.
A reflex angle is an angle that looks like a reflection of a ray. A reflex angle is an angle that is greater than $${180}^{\circ }$$ but smaller than $${360}^{\circ }$$. It is as shown in the figure.

To solve this question first we assume an angle greater than $${180}^{\circ }$$ whose reflex angle is formed.
Let us assume the angle is $${200}^{\circ }$$
Now we will subtract this angle from total angle $${360}^{\circ }$$ and then make that angle in the opposite direction and then we represent that from the opposite direction and that is a reflex angle.
Hence, we will make the angle of:
${360}^{\circ }-{200}^{\circ }={160}^{\circ }$
We can simply draw the angle of ${160}^{\circ }$ using a protractor. We should draw this angle in the opposite direction.

For any general reflex angle, we have to make a reflection angle from an anticlockwise direction. Then we make the subtracted angle from a clockwise direction and mark that the reflex angle from the reference line.

Note:
This question tests our basics, the definition of reflex angle and how to draw an angle using a protractor. We have to remember them in order to answer such questions. We have to remember that we need to draw the subtracted angle in the opposite direction.
