This 11-plus Maths quiz on shapes is going to be about triangles and their properties: triangles are very, very important in geometry. They say two is company but three is a crowd; unfortunately, you need three sides to make a triangle.
How many 3-sided shapes can you think of? There is only one - the triangle. However, there are many different types of triangles - how many can you remember? This quiz will test you on some of them.
Did you play our first quiz on shapes - and did you attempt to draw a pig using only circles? If you enjoyed that exercise, see if you can draw a cat using only triangles.
But first, it's time to play our quiz - as always, don't move on until you've got all ten questions correct.
