Are solutions available?" Comment recorded on the 18 September 'Starter of the Day' page by Mrs. Peacock, Downe House School and Kennet School: "My year 8's absolutely loved the "Separated Twins" starter. I set it as an optional piece of work for my year 11's over a weekend and one girl came up with 3 independant solutions."

Level 1  Name and find the size of the angles in regular polygons.
Level 2  Find the size of the angles marked with letters in simple diagrams.
Level 3  A mixture of problems related to the angles in polygons.
Each exterior angle of an nsided regular polygon is 360° ÷ n
Each interior angle of an nsided regular polygon is 180° − 360° ÷ n
The sum of the exterior angles of any polygon is 360°.
The sum of the interior angles of an nsided polygon is (180n − 360)°.
Interactive animation showing why exterior angles add up to 360°
