Elaborations
- • Elaboration using strips of paper with parallel sides to make triangles and quadrilaterals, and contrasting the rigidity of triangles with the flexibility of quadrilaterals
- • Elaboration constructing triangles with 3 given side lengths and discussing the question, “Can any 3 lengths be used to form the sides of a triangle?”
- • Elaboration identifying and communicating about side and angle properties of scalene, isosceles, equilateral, right-angled, acute and obtuse triangles using geometric conventions
- • Elaboration describing, comparing and contrasting squares, rectangles, rhombuses, parallelograms, kites and trapeziums, explaining the relationships between these shapes
