where you draw three extra triangles, not just one, and they surround a square of c x c. Think about it as making two copies of the trapezoid, one rotated on top of the other.
- sorokod 11mo agoI shared this one with my son, the step where the 2ab expressions cancel out gave him a little aha moment.
- procrastitron 11mo agoThis was exactly what I thought of as well. Garfield’s version seems more complicated since you have to calculate the area of a trapezoid instead of the area of a square, but conceptually they are the same.
