Area of a Triangle
A super quick tutorial on finding the area of a triangle.
Tip: Like I said in the movie: you could half either the base or the height before multiplying, or you can multiply them and half it at the end. Of course, I usually find it easiest to half whichever is even.
So, if the base is 19 and the height is 20, I'd half the height to get 19 X 10, with is easier on my brain.
