The perimeter of this yard is the distance around the outside of the yard, indicated by the red arrow; It is measured in linear units such as feet or meters. To find the perimeter of a polygon, take the sum of the length of each side. The polygons below are much smaller than a fenced-in yard.

The angles on the inside are called Interior angles. The sum of the interior angles of a triangle is always 180 degrees. The exterior angle is the angle between any side of a shape, and a line extended from the next side. The sum of an exterior angle and its adjacent interior angle is also 180 degrees.

Calculate the interior angle, by multiplying 180(n - 2) where “n” is the number of sides -- in this case, six. Multiply 180 and 4 to get the answer. Divide this by the number of angles, which is six. This will give you the measurement in degrees of each angle, which should be 120.

Polygons - Quadrilaterals. So, the sum of the interior angles of a quadrilateral is 360 degrees. All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the interior angles, we know that the sum of all the angles is 360 degrees (from above)...

To find the diagonals of hexagons, use the formula: n (n-3)/2, where n is the number of sides of a polygon. For a hexagon, n = 6, and 6 (6-3) / 2 equals nine diagonals. A regular hexagon shape has a radius that equals the side length.
