Estimate, measure and compare angles using degrees

• Identify the arms and vertex of an angle where both arms are invisible, such as for rotations.

• Explain how a protractor is formed and used to measure an angle.

• Estimate and describe the size of angles using known angles as benchmarks.

• Record angle measurements using the symbol for degrees (°).

Use a protractor to measure and identify types of angles

• Recognise that a right angle is 90°, a straight angle is 180° and an angle of revolution is 360°.

• Identify and describe angle size in degrees for the classifications acute, obtuse and reflex.
