Example Question #1 : Hexagons
If a triangle has 180 degrees, what is the sum of the interior angles of a regular octagon?
The sum of the interior angles of a polygon is given by where = number of sides of the polygon. An octagon has 8 sides, so the formula becomes
Example Question #1 : How To Find An Angle In A Hexagon
Find the sum of all the inner angles in a hexagon.
To solve, simply use the formula to find the total degrees inside a polygon, where n is the number of vertices.
In this particular case, a hexagon means a shape with six sides and thus six vertices.
