Jonathan's Key:

  • Quadrillaterals are blue; I know this because they have 4 sides.
  • Right angle triangles are light brown; they have one right angle, 3 sides and 3 angles.
  • Scalene triangles are pink; I know this because I went on the computer and found out a scalene triangle has 3 unequal sides and 3 angles.
  • Irregular pentagons are black; they have 5 unequal sides and angles.
  • Obtuse triangles are green; these are triangles with one obtuse angle.

Great use of colours and patterns to differentiate between triangles, quadrilaterals and pentagons.
