Thread: triangle proof

have to make these to formulas equal each other

Area of a triangle= 1/2 bc sinA

Area of a triangle= 1/2 bh

i figures out one step:

Make both equations equal each other::: 1/2 bh = 1/2 bc sinA

i have to figure out how to break it down to prove they are equal....

From the definition of sin(a) you can find that h=csin(a) .

now i am stuck

I don't understand what you're asked for...

You're asked to make them equal to each other.

They both give the area of a triangle.

Therefore they are equal...
