Class 5 Maths Worksheet: Angles
The method (Know the totals): Acute < 90°, right = 90°, obtuse between 90° and 180°, straight = 180°. On a straight line: the two angles add up to 180°. In a triangle: the three angles add up to 180°. Around a point: 360°. Clock: each hour mark is 30° apart (360° ÷ 12).
