Triangle Congruence and Understanding Polygons

At A Glance:

• the area for a triangle is 1/2B*H
• Large polygons can be divided into triangles

within this square, if we know the hypotenuse of one, we an find the length of the diagonal


if you make triangles out of the diagonals, you can easily find the area. if we know the base length, we can use that to find the area of on triangle, than we would just have to multiply that by eight.
