In maths , we are learning all about 2D shapes. Today we learnt how to draw shapes with given properties. We worked in co-operative groups to draw triangles, quadrilaterals, pentagons and hexagons with one or more of the following properties:
– two acute angles
– two obtuse angles
– two right angles
– two pairs of parallel lines
– two pairs of perpendicular sides.
We discovered that only one of these can work in a triangle… Can you work out which?
