In your exciting KS3 Maths adventures, you've learned lots about shapes. Polygons have certain properties - angles, side lengths, perimeter and area. Some rules apply to all polygons, some are just for regular ones. There are also some properties which apply only to 3D shapes, like volume or capacity, and face numbers. Now, let's dive into a new property and discover the world of symmetry with this quiz!

Think of lines of symmetry like magical reflections. Picture placing a mirror on a shape - if it has a line of symmetry, the mirror shows an exact copy. Try it out, it's like a fun game! The key is to mentally cut the shape in half with an imaginary mirror. Are both sides identical, or is one a bit 'lopsided'?
After your mirror adventures, test your knowledge of symmetry types with the quiz below. Take your time, think it through, and good luck!

A rectangle can be rotated about its centre into two positions and look exactly like the original rectangle. This is rotational symmetry

H has two, M and T have one, S has none

As two of its sides are of equal length then isosceles tringles have one line of symmetry

Though you can't 'cut' a parallelogram into two reflective parts, you can rotate it to 'fit' in two positions

Kites will only cover the same place in one position. If you rotate them less than 360o they will no longer fit the gap

In fact it has two. You can draw a line vertically and another horizontally to see them more clearly

Three of the planes run parallel to the faces of the cube, and the other six run diagonally from one edge to its opposite

Think of two halves, separated by a vertical line running down the centre of the plane from nose to tail
