area, perimeter, and corresponding

Today while we were correcting homework we talked about how hight and base meet at a 90 degree angle. When finding an area always do ase times hight. If it's a triangle then you would do the base times the hight times one half. In order to compare the parts of these triangles we use the terms corresponding sides. and corresponding angles. The rectangles angles are all 90 degrees. Corresponding can be sides or angles. It is also the same position on both sides. we learned today that corresponding means to be similar in many ways.
