ANGLE FACTS

1. An angle measures a turn, in degrees (°). A full turn is 360°, half a turn is 180°, a quarter turn is 90°.
2. Acute is less than 90°, right is exactly 90° (a square corner), obtuse is between 90° and 180°, straight is 180°, and reflex is more than 180°.
3. A protractor has two scales. Start from the 0 where one line of the angle lies, and count round from there.
4. Angles on a straight line add up to 180°. Angles in a triangle add up to 180°. Angles all the way round a point add up to 360°.
5. Bearings start at North (0°) and turn clockwise: East 90°, South 180°, West 270°.
6. Archer levels: drag on the picture to aim the bow, then tap Fire. 0° points right along the ground, 90° straight up, 180° left.
7. Each level has 10 questions. 10 right for 3 stars, 8 for 2, 6 for 1.
