GCSE Maths Interior Angles Help?

I dont understand what you mean by that but this might come in handy, when wanting to find the interior angles of a shape. E.g a square, it would be 360 divided by 4 considering the sqaure has four sides and a circle, sqaure ect is 360 degrees. 360 divided by 4 = 90. 180 take away 90 = 90. 180 because a straight line is 180 degrees and you must draw a straight line on the bottom of the shape in order to help you. Therefore the interior angle would be 90 degrees. Sorry couldn't help you with your question. :)
