Estimating - Reversed With Reference (Level 3)

This math topic focuses on practicing geometric skills related to angles. The tasks include estimating angles, with an emphasis on reversed referencing, as part of a larger unit on Geometry - Angle Basics. Students are given a displayed angle value and need to identify another given angle. The problems mainly concentrate on recognising common angles such as 15°, 30°, 45°, 90°, 120°, and 135°.
