Help your students prepare for their Maths GCSE with this free polygons worksheet of 44 questions and answers
Polygons are 2 dimensional shapes made from three or more straight lines. Some types of polygons, with their number of sides in brackets, are: all types of triangles (3), including equilateral triangles and isosceles triangles and all types of quadrilaterals (4), including trapezoids and rhombuses. Other polygons include pentagons (5), hexagons (6), heptagons (7), octagons (8), nonagons (9) and decagons (10).
There are regular and irregular polygons. Regular polygons are polygons where all of the sides are equal in length and all of the angles are the same whereas irregular polygons can have sides and angles of varying sizes. E.g. a regular hexagon has 6 equal sides and 6 equal interior angles.
For all polygons, the sum of the exterior angles is 360° and the sum of the interior angles is (n-2)*180° . Since the angles in regular polygons are all equal, the size of each interior angle of a regular polygon can be found by dividing the sum of the interior angles by the number of sides. For example, a regular pentagon has 5 sides and therefore the sum of the interior angles is (5-2)*180=540° , and each interior angle is 108° (540 divided by 5). In irregular polygons, knowing the sum of the interior angles for a polygon allows us to work out a missing angle within that polygon.
We can classify polygons using properties of polygons such as number of sides, any equal sides or angles and whether there are any parallel lines or lines of symmetry.
Looking forward, students can then progress to additional geometry worksheets, for example a 3D shapes worksheet or an area of a triangle worksheet.
