![]() Scroll down to the practice questions to have a go at some of these yourself. The diagram below shows some examples of shapes which are symmetrical, shapes which aren’t symmetrical and where the correct lines of symmetry should be drawn. Alternatively, you may be given a shape and asked whether or not it has a vertical line of symmetry and if so to draw it on with a ruler. You may be shown a shape with a vertical line through it and asked whether or not the line is a line of symmetry. How to find a line of symmetry in symmetrical shapesĬhildren studying KS1 primary school maths will need to learn how to find vertical lines of symmetry in year 2. Below is a guide on how to find lines of symmetry for a variety of shapes. Some irregular shapes have lines of symmetry, but the more irregular a shape is, the less likely it is to have a line of symmetry. Some shapes have no lines of symmetry, some have one and some have many! Regular shapes always have lines of symmetry, and the number of lines of symmetry is equal to the number of sides of the shape. Here are some examples of lines of symmetry in nature: Equivalently, if you were to place a mirror along the line of symmetry, the shape would be unchanged. A line of symmetry of a shape is a line which cuts the shape perfectly in half so that if you were to fold the shape along the line, both halves of the shape would overlap each other exactly.
