Question

How many right angles make a complete angle?

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is D 4

The measure of a complete angle is ${360}^{\circ }$ and the measure of a right angle is ${90}^{\circ }$.
So, number of right angles in a complete angle = $\frac{{360}^0}{{90}^0}=4$
So, 4 right angles make a complete angle.
