Measuring angles (age 11+)
Draw and measure line segments and angles accurately using ruler and protractor, and interpret scale drawings to extract real measurements
Suggested ages 11–13
Evidence of understanding
- Draw a triangle accurately given two sides and the included angle (SAS)
- Measure angles in a geometric figure to the nearest degree using a protractor
- Read a scale drawing to determine actual lengths, explaining the scale used
Assessment prompt
If Measuring angles (age 11+) is given an architect's floor plan where 1 cm represents 2 m, can they measure a room on the plan and work out its real-world dimensions?
