can u giv me one example? can steps to do it? thanks alot
ya...
Similar triangle:
Lets say you have six vectors, A, B, C, D, E, F.
Suppose ABC forms a triangle and DEF for another triangle.
Find AB, AC, BC, DE, DF and EF.
ABC is similar to DEF if AB/DE = AC/DF = BC/EF, though it is not
necessary in this order.
Finding Area:
Lets say you are given three vectors X, Y and Z.
Find XY, XZ and YZ first.
Now, using Heron's formula, you will have S = 1/2 x (XY +XZ
+YZ)
The area of the triangle will be sqrt ( S x (S-XY) x (S-XZ) x
(S-YZ) ).
