I studied parallelograms and triangles and I got to the formula of the area of both of them.
Namely, 1absinA/2 or absinA.
Naturally, an area of a triangle is also 1bh/2.
So, if we mash them up, considering that sinA=c/b
1/2 x bh = 1/2 x ab x c/b
Could this mean that bh=ac?
But this formulas work for both right angled triangles and non-right angled triangles, right?
So we can't consider sinA=c/b at all times, since the angle is not always right.
Does this has -something- to do with the Law of Sines or Cosines?
Sorry if I haven't made myself clear.
