**In this quiz about shapes we are going to look at quadrilaterals:** these are closed 2D (two dimensional) shapes: being 2D they are flat and have no volume.

The word 'quadrilateral' comes from two Latin words, 'quadri' and 'latus'. Quadri means four and latus means side. Think of a quad bike - why is it called this? Because it has four wheels. If you hear of someone giving birth to 'quads', you'll now know how many babies there would be.

Going back to shapes, the obvious quadrilateral is a square, but there are many, many more. Do this 11-plus Maths quiz and see how much you know about the properties of quadrilaterals.

If you want to draw an animal using only quadrilaterals, try a cow - good luck!

What is the sum of the interior angles of a quadrilateral?

180°

720°

360°

270°

A quadrilateral can be split into two non-overlapping triangles: 180° + 180° = 360°
