There are LOADS of angles to find here in this layering of regular polygons. Students start by finding the interior angles they know but soon have to use irregular polygon properties, parallel lines, angles round a point at more. This is differentiated by outcome and should keep even the brightest sparks busy for a while especially trying to find the angles in the white polygons that are not shaded.

Love this problem. I believe there may be a mistake in the key. I think the angle near the top on the left that is shared between the pentagon and triangle should be 48 degrees instead of 45.
