Based on an image from NCTM, pupils have to work out all of the angles in each polygon in the diagram. A couple of necessary facts are given to start, namely the 20 degree angle, the fact that triangle W is isosceles and that S is a regular hexagon and a couple of right angles. Answers on page 2.

Very nce resource, thanks. If we want to discourage students from making assumptions based on what they see then we also need to say that J & R are parallelograms, I & N are rhombuses (rhombi?) and K is symmetrical.

Still a good resource, challenges students to use a mix of angle facts.
