How can you tell if two triangles are similar

http://www.math.com/school/subject1/lessons/S1U2L4DP.html WebIf you know that two objects are similar, you can use proportions and cross products to find the length of an unknown side. Let's find the length of side DF, labeled x. We read this proportion as: "AC is to AB as DF is to DE." Now, substitute in the lengths of the sides. Take the cross product to get the equation.
