Properties of shapes

• Identify 3-D shapes, including cubes and other cuboids, from 2-D representations
• Know angles are measured in degrees: estimate and compare acute, obtuse and reflex angles
• Draw given angles, and measure them in degrees (°)
• Identify:
• Angles at a point and 1 whole turn (total 360°)
• Angles at a point on a straight line and half a turn (total 180°)
• Other multiples of 90°
• Use the properties of rectangles to deduce related facts and find missing lengths and angles
• Distinguish between regular and irregular polygons based on reasoning about equal sides and angles
