Question

How many right angles need to be put together to make:

a.) 360 degrees?
b.) 180 degrees?
C.) 270 degrees?
d.) A straight angle?

Answer 1

A 180° angle is called a straight angle. Angles such as 270 degrees which are more than 180 but less than 360 degrees are called reflex angles. A 360° angle is called a complete angle.

Answer 2

A. 4

B. 2

C. 3

D. 2

Explanation:

Multiplication!!! Always remember that a right angle is 90 degrees, also a straight angle is 180 degrees..

Remember like this:

90 x 1 =90

90 x 2 =180

90 x 3 = 270

90 x 4 = 360
