its a formula devised by a guy named heron i believe for finding the area of a triangle from its side measures
i never recall the actual formula tho
this book wants a geneal formula with a and b . note the triangle is a right triangle
ba/2 is the answer how did the book up with that answer
a = height' b = base; and divide it in half sine that is the area of the tris rectangle
|dw:1328028726662:dw| how is a the height
easy, call it a heaight
tip it over onto b if you want; the measures dont change
oh so you choose which side is your height
yes; since there are only 2 sides; and b*a = a*b it makes no difference what you actually want to call them ...
so in the picture that i drew b look like the height of the triangle
then call b height
its side b .... regardless of anyting else, the math doesnt really care ....
say b=3 and a=2 does 2*3 = 3*2?
okay so it doesnt matter which is a which is b
okay thanks i thi thought the height of the triangle is the part that is vertical
only to those who cant do math :)
|dw:1328029066746:dw| which one is height now?
can i ask you to please look at another question of mine had trouble with it
