Question

How many right angles will be required to make ${720}^{\circ }$?

• A. $3$
• B. $6$
• C. $8$
• D. $4$

Answer 1

The correct option is C $8$

A right angle has a measure of ${90}^{\circ }$.


Number of right angles required to form ${720}^{\circ }$ angle will be $\frac{{720}^{\circ }}{{90}^{\circ }}=8$.

We can look into another way, that $4$ right angles can make one rotation around circle.


And, we know that to make ${720}^{\circ }$ we have to rotate two complete rounds of a circle.

So, $4+4=8$ right angles will be required to make ${720}^{\circ }$ angle.
