# Year 5: Geometry: properties of shapes

New Maths Curriculum (2014): Year 5 objectives.

Pupils should become accurate in drawing lines with a ruler to the nearest millimetre, and measuring with a protractor. They use conventional markings for parallel lines and right angles.

Pupils should use the term diagonal and make conjectures about the angles formed by diagonals and sides, and other properties of quadrilaterals, for example using dynamic geometry ICT tools. Pupils should use angle sum facts and other properties to make deductions about missing angles and relate these to missing number problems.

 Identify 3-D shapes, including cubes and cuboids, from 2-D representations Know angles are measured in degrees; estimate and measure them and draw a given angle, writing its size in degrees (°) Identify: multiples of 90°, angles at a point on a straight line and ½ a turn (total 180°); angles at a point and one whole turn (total 360°); reflex angles; and compare different angles Draw shapes using given dimensions and angles State and use the properties of a rectangle (including squares) to deduce related facts Distinguish between regular and irregular polygons based on reasoning about equal sides and angles
