Worksheet for measuring angles in degrees, including identifying angle types, drawing clock hand positions, and determining compass directions after specific turns.

Here are the answers to your worksheet, broken down by section.

Section 1: Measuring Angles in Circles

Rule: A full circle is $360^{\circ}$. We need to find the size of the shaded part.

* a) The circle is cut into 2 equal parts.
* Calculation: $360 \div 2 = 180$.
* Type: An angle of exactly $180^{\circ}$ is a straight angle.
* b) The circle is cut into 4 equal parts, and 1 is shaded.
* Calculation: $360 \div 4 = 90$.
* Type: An angle of exactly $90^{\circ}$ is a right angle.
* c) The circle is cut into 4 equal parts, and 3 are shaded.
* Calculation: $90 + 90 + 90 = 270$ (or $360 - 90 = 270$).
* Type: An angle bigger than $180^{\circ}$ but less than $360^{\circ}$ is a reflex angle.
* d) The circle is cut into 4 equal parts, and 2 are shaded (which makes half a circle).
* Calculation: $90 + 90 = 180$.
* Type: This is a straight angle.

Section 2: Drawing Clock Turns

* a) A clockwise $180^{\circ}$ turn:
* Start at 12.
* A $180^{\circ}$ turn means going halfway around the circle.
* Opposite of 12 is 6.
* Action: Draw the minute hand pointing straight down at the 6.

* b) An anti-clockwise $90^{\circ}$ turn:
* Start at 12.
* "Anti-clockwise" means going backwards (to the left).
* A $90^{\circ}$ turn is one-quarter of the circle.
* Going back from 12 leads to 9.
* Action: Draw the minute hand pointing straight left at the 9.

Section 3: Compass Directions

* a) $180^{\circ}$ clockwise turn from E (East):
* Face East.
* Turn $180^{\circ}$ (halfway around).
* You will be facing the opposite direction. Opposite of East is West.
* Answer: W (West)

* b) $270^{\circ}$ anti-clockwise turn from W (West):
* Face West.
* Turn Left (anti-clockwise).
* West $\rightarrow$ South ($90^{\circ}$)
* South $\rightarrow$ East ($180^{\circ}$)
* East $\rightarrow$ North ($270^{\circ}$)
* Answer: N (North)
