Answers: 1 Show answers. The following diagram shows a regular hexagon: Note that, for any point in a polygon, the interior angle and exterior angle are on a straight line and therefore add up to 180°. the concept of perimeter that perimeter of a regular polygon is the sum of the lengths of the sides of the polygon , if we have n sides each with length ‘S’ then the sum of the lengths of these sides will be nS. Every polygon has three or more sides (if it had fewer than three, it wouldn’t really be a shape at all). If you have looked at the page entitled "Regular Polygons", you may recall that a polygon is a closed, two dimensional figure with multiple (i.e. ΔABC ~ ΔXYZ. KS3 Level 1-3.

There are different types of regular polygons. If we add the three angles of a triangle physically by cutting them off and lining up the vertices and sides, then the three angles form a straight angle. The side of the polygon is 10ft and the top sides of the polygon is 11ft. Similar Polygons . The diameter of the moon is about 3500 km. When a polygon's sides are the same length and angles are the same degree, we call it a "regular" polygon. Take a look at the differences: 1. What is the value of x?
