Say, there are two triangles with corresponding sides equal. Does that guarantee they have the same area? Thanks math wizs!
Yes it does. Then they are congruent triangles with SSS congruency. The areas of congruent triangles are equal.
Moreover, the area of a triangle in terms of its sides is square root of s(s-a)(s-b)(s-c) where s=(a+b+c)/2.
