**mathematics Five Angles in a Star - Stack Exchange**

Internal angle sum of a polygon, angle sum of a pentagon, angle sum of a hexagon and external angle sum of a polygon. Year 8 Interactive Maths - Second Edition. Internal Angle Sum of Polygons Consider the angle sum of a quadrilateral. Clearly, the diagonal AC divides the quadrilateral into 2 triangles. Consider the angle sum of a pentagon. Clearly, the diagonals AC and AD divides the pentagon... Since the exterior angle is the supplement of the interior angle (that is the two angles together add up to 180) then the interior angle is 180-45=135. (The sum would be 135x8). (The sum would be 135x8).

## How To Find The Sum Of Interior Angles

### When we add up the Interior Angle and Exterior Angle we get a straight line 180Â°. They are "Supplementary Angles". The Exterior Angles of a Polygon add up to 360Â° In other words the exterior angles add up to one full revolution. Press Play button to see. (Exercise: try this with a square, then

- To find the sum of the interior angles of a hexagon, use the formula 180(n-2) where n is 6 so 180(4)=720 degrees. To find the measure of one angle in the regular hexagon, divide that number by 6 and we have 120 degrees.
