4/10/2011 · Best Answer: interior angles will add up to the amount of sides the shape has (n) minus 2, multiplied by 180 degrees, therefore the equation for each interior angles in a regular polygon is: 180(n-2)/n So, if it has 12 sides, (180 x 10)/12 = 150 degrees The exterior angles for a regular polygon …... Figure 2 The (nonstraight) exterior angles of a polygon. Theorem 40: If a polygon is convex, then the sum of the degree measures of the exterior angles, one at each vertex, is 360°. Example 1: Find the interior angle sum of a decagon.

While the exterior angle s the angle between any side of a shape, and a line extended from the next side. Properties of a Convex Polygon A line drawn through a convex polygon will intersect the polygon exactly twice, as can be seen from the figure on the left.... 24/05/2011 · Find out why Close.

**How to find out how many sides a regular polygon has?**

Your student or child will need to know to how to calculate the angles of polygons. Cazoom Maths have supplied a number of various different polygon worksheets along with the answers and formulas. Your student or child will soon be a pro at identifying different types of polygons, as well as calculate the interior and exterior angles of regular and irregular polygons. All of our worksheets are... The easiest way to do this is to find out the interior angle and divide that number into 360. (The figure is regular meaning all sides are equal. And so are all interior angles…

**Interior and exterior angles of a polygon Math Central**

The easiest way to finding the number of sides, is to first find out the exterior angle. So let’s say the interior angle given is 144°, how to find the number of sides in the polygon? First step is to calculate the exterior angle, which in this case = 180° – 144° = 36°... A 10-sided polygon has 10 angles. To work out how many degrees each angle has, split the polygon into triangles. (a triangle is 1 triangle, a 4-sided figure splits into 2 triangles, a pentagon splits into 3 triangle, a hexagon into 4 triangles… etc.)
