classify triangles, quadrilaterals and other polygons according to their side and angle properties; identify and reason about relationships

Elaborations

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