Angles in Irregular Polygons WORKSHEET DESCRIPTION
This worksheet focuses on dealing with the sum of the angles in polygons and looks mainly at irregular polygons.
Section A has a table to complete with a diagram of polygons with an increasing number of sides, featuring a missing angle.
Section B asks for a missing angle from some irregular polygons. An extension activity then poses questions about the angles in a diagram featuring a regular octagon.
