Question 1: Can you guess how many degrees is the angle which is
- 12 of a right angle __________
- 13 of a right angle __________
- 2 times of a right angle __________
Answer:
We know
1 right angle = 90°
- 12 of a right angle =12× 90° = 45°
- 13 of a right angle =13× 90° = 30°
- 2 times a right angle = 2 x 90° 180°
