Angles in polygons
A KS4 PowerPoint resource that introduces students to the sum of angles in a polygon by splitting the shape into triangles. The first 8 slides are used for students to find the number of triangles in 8 different shapes. They use a table on slide 9 to summarise their results and find the formula. The answers are provided on the final slide.
