It may be useful to refer to M1 properties of angles; M1 properties of 2D shapes and M5 Polygons if necessary. The sum of the angles inside any polygon can be found by spitting the polygon into ...
A nonagon has nine sides and a decagon has ten sides. To understand polygons, a good understanding of other angle rules, including triangles and quadrilaterals can be helpful. The word for the name of ...
Before reading this guide, it may be helpful to read the guides from Module 1 on the properties of angles and the properties of 2D shapes. The sum of the angles inside any polygon can be found by ...
Polygons are two dimensional shapes with straight sides. They can be described by the number of sides they have and whether the shape is regular or irregular. Where the straight sides of the polygon ...
A shape has a line of symmetry when the folded part sits perfectly on top with all edges matching. The number of lines of symmetry in a regular polygon is equal to the number of sides. A shape has ...
A rectangle has two pairs of equal sides. It has four right angles (90°). The opposite sides are parallel. The diagonals bisect each other. A parallelogram has two pairs of equal sides. It has two ...
