AC9M8SP02

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

Elaborations

AC9M8SP02_E1 - 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 \(360\)°
AC9M8SP02_E2 - identifying properties of quadrilaterals related to side lengths, parallel sides, angles, diagonals and symmetry
AC9M8SP02_E3 - applying the properties of triangles and quadrilaterals to construction designs such as car jacks, scissor lifts, folding umbrellas, toolboxes and cherry pickers
