Is this explaination correct?
Here is the question:
Explain how the formula for the area of a triangle is derived from that of a rectangle.

Here is my answer:

You can make a triangle into a rectangle by doubling it, because of that fact, you know that the area of a triangle is half the area of a rectangle. Or that the area of a rectangle is double the area of a triangle.

Seems fine, although some triangles need to be split into two:|dw:1331314100355:dw|

I hope it's not cut off in the picture! If it is, try making your window full-screen :)

Oh, very true. I just assumed they meant right triangles.
