·    Use a ruler and protractor to:

- construct a triangle given two sides and the included angle (SAS) or two angles and the included side (ASA);

explore these constructions using ICT.

Construction

(220–223)

 

Use a ruler and protractor to construct simple nets of 3-D shapes, e.g. cuboid, regular tetrahedron, square-based pyramid, triangular prism.
