I want to say 2, once at each corner
A polygon can be used infinitely many times!
The area of a four-sided polygon is base times height.
13 triangles will go into a 13-sided polygon.
That's easy enough. In any n-sided polygon, each of the n verticies is the endpoint of n - 3 diagonals, because any of the other endpoints is a different vertex on the polygon, other than the the opposite endpoints on the sides to which the vertex belongs.At the same time, if you do this, all the diagonals are counted twice, because segment AB is the same as segment BA. Therefore, you divide by 2 and get n(n - 3)/2.So, for example, consider the pentagon. Each of the five vertices has two others with which a diagonal could be drawn, because there's four other vertices and two already have this one for a side. So five times two is ten, but each was counted twice, so we divide by two, and half of ten is five, the correct answer.

Because there are 4 sides of the polygon.
Draw a straight line segment. From one of its ends, draw another straight line segment. From the end of this straight line, draw another straight line segment which does not touch any of the existing lines. Repeat the same 5 more times. From the end of this last line, draw a straight line to the start of the first line. You may need to tweak some of the intermediate lines so that the last line does not intersect an existing line. That is it! A plane area enclosed by 9 straight lines = a 9-sided polygon.

Divide the numbers that are diagonal from each other, but there are times when this does not work.

area of a polygon is the amount of area inside the polygon. A square is a polygon and its area is the side length squared, ie times itself. Some polygons are harder to find the area of.
a=apothem n=number of sides on the polygon A squared times cos(pi over N) times sin (pi over N) times N

Providing that it is a regular polygon it will have 8 sides.
