We can group 2D shapes into categories using their features. A shape with $4$4 straight edges is a quadrilateral.

This video looks at the names of some 2D shapes and what features they have.

question 2

Remember!

To help work out the name of a shape, think about properties like:

  • how many sides it has
  • what sides are the same length
  • does it have right angles
  • are the sides straight or curved
  • how many vertices, or corners, it has
