Q6: For each arrow turn, guess the size in degrees and state the type.
(a) 1 quarter turn clockwise → ______ ° → type: __________
(b) 3 quarter turns anti‑clockwise → ______ ° → type: __________
(c) 1/2 of a full turn → ______ ° → type: __________
(d) 2/3 of a full turn → ______ ° → type: __________
(a) 1 quarter turn clockwise
= 90°
→ type: Right angle
(b) 3 quarter turns anti-clockwise
= 3 × 90° = 270°
→ type: Reflex angle (since it’s more than 180° but less than 360°)
(c) 1/2 of a full turn
= 360° ÷ 2 = 180°
→ type: Straight angle
(d) 2/3 of a full turn
= (2/3) × 360° = 240°
→ type: Reflex angle
Q7: A robot starts facing East. It makes the following sequence of turns:
- 1 quarter turn clockwise,
- 1 half turn anti‑clockwise,
- 3 quarter turns clockwise.
(a) What direction is it facing now? __________
(b) What is the net turn (in degrees) relative to the start? __________°
Ans:
Start: Facing East.
- 1 quarter turn clockwise → from East → South.
- 1 half turn anti-clockwise → from South → turn 180° left → North.
- 3 quarter turns clockwise → 270° right from North → West.
So final direction = West.
Now, net turn relative to start (East):
- East → West is a 180° turn.
- Since the robot ended up on the opposite side of its start, the net turn is ±180°.
- Conventionally, we write it as −180° (anticlockwise) or +180° (clockwise)
Final answers (a) West
(b) Net 180°
