establish properties of quadrilaterals using congruent triangles and angle properties, and solve related problems explaining reasoning

Elaborations

• 1 establishing the properties of squares, rectangles, parallelograms, rhombuses, trapeziums and kites using geometric properties and proof, such as the sum of the exterior angles of a polygon is equal to a complete turn or \(360\)°
• 2 identifying properties of quadrilaterals related to side lengths, parallel sides, angles, diagonals and symmetry
• 3 applying the properties of triangles and quadrilaterals to construction designs such as car jacks, scissor lifts, folding umbrellas, toolboxes and cherry pickers
