Objective

NNS

Possible Resources

Use correctly the vocabulary, notation and labelling conventions for lines, angles and shapes.

 

Identify parallel and perpendicular lines; know the sum of angles at a point, on a straight line and in a triangle and recognise vertically opposite angles.

(178–189)

 

Begin to identify and use angle, side and symmetry properties of triangles and quadrilaterals.

Use conventions and notation for 2-D coordinates in all four quadrants; find coordinates of points determined by geometric information.
