Solution:

Concept- Angles are measured in degrees. There are 360 degrees in a circle. A right angle, for instance, is 90 degrees. Ninety degrees would be expressed as 90° since the sign for a degree is °. The radian is yet another angle measurement unit.
One right angle is equal to

90 °

, Using the unitary method to calculate the degree.
Given is that one right angle

= 90 °

1) One right angle

= 90 °

2) Two right angles

= 90 ° \times 2 = 180 °

3) Three right angles =

90 ° \times 3 = 270 °

4) Four right angles

= 90 ° \times 4 = 360 °

\frac{2}{3} Right angle = 90 ° \times \frac{2}{3} = 60 °

1 \frac{1}{2} Right angle = 90 ° \times 1 \frac{1}{2} = 135 °

Hence, the correct option is 3)

90 °, 180 °, 270 °, 360 °, 60 °, 135 °

How many degrees are there in:1) One right angle2) Two right angle 3) Three right angle4) Four right angle5) $\frac{2}{3}$ right angle

6) $1 \frac{1}{2}$ right angle
