All polygons can be broken up into triangles...
For a Regular Shape (all angles measure the same), you can split it up into triangles to find the total angle measures. For example, in a square, you can only split it in half, making 2 triangles (below). A triangle always measures 180 degrees, so for an octagon you would split it into triangles from one point. If you count the triangles, you will have 8 triangles. Now Multiple 8 by i80, and your sum of angles will be 1080°.If you then divide it by the sum of the angles in a triangle, or 180 degrees, you will find that 1 angle measures 135 degrees. This rule applies to all Regular Polygons. If you still don't get it,try the link below

Exterior angles of both polygons add up to 360 degrees
All triangles are polygons, having three straight-line sides. However, a right triangle is not a "regular polygon" because the three side lengths and interior angles cannot be the same (the right angle takes up 90 degrees of the total 180). An equilateral triangle is a regular polygon.

For instance, you might divide the polygons into triangles, calculate the area of each triangle, and then add everything up.

Triangles or squares or hexagons. There are also mixtures, like octagons plus squares.
Yes, a triangle is a polygon.A polygon is any closed figure made up of 3 or more line segments. The triangle qualifies, and it is the "most simple" polygon as it has the least number of sides.A triangle is most certainly not a ploygon. However, it is a polygon.
It is because it is made up of triangles. The force is split. Simple.
The easiest method is to split the octagon up into triangles and sum the areas of the triangles.
