Question

Can you guess how many degrees is the angle which is ―
• $\frac{1}{2}$ of a right angle __________

• $\frac{1}{3}$ of a right angle __________

• 2 times of a right angle __________

Answer 1

We know

1 right angle = 90°

• $\frac{1}{2}$ of a right angle = $\frac{1}{2}$ × 90°

= 45°

• $\frac{1}{3}$ of a right angle = $\frac{1}{3}$ × 90°

= 30°

• 2 times a right angle = 2 × 90°

= 180°
