The number of lines of symmetry in a regular pentagon is five. Show your child examples of shapes with different symmetry. They should be able to draw and label all of the lines of symmetry on the shape. If they are unable to draw all of the lines correctly, trace them in a different colour.

A regular pentagon has five lines of symmetry, one running from each vertex to the midpoint of the opposite side. An irregular pentagon can have no lines of symmetry, or it can have one line. In either case, you need to draw a line from the middle of each vertex to the opposite vertex.

The number of lines of symmetry in a regular polygon is equal to the number of sides of the shape. There is also rotational symmetry, which allows a shape to be rotated in a circle and still look the same. This symmetry has an order, which refers to the number of times a shape can rotate in a full circle.

A pentagon has five lines of symmetry, while a hexagon has six. The number of lines of symmetry varies from polygon to polygon. Generally, the more sides, the greater the symmetry. A square, for example, has four lines of symmetry. An isosceles trapezium, on the other hand, has one line of symmetry.
