Maths Challenge - polygons and angles

Use the rule ... to find the total degrees of all the angles in a polygon you need too
1) count the number of sides of the shape
2) subtract 2
3) finally multiply that number by 180
4) the answer is the total amount of degrees for that shape.
E.g. Triangle
3 sides - 2 = 1
1 x 180 = 180 degrees (all the angles in a triangle add up to 180 degrees)
Can you work out the total degrees of all the polygons from a triangle to a 10sided shape? Complete you work on paper or in your jotter, show your working out.
