Hence they would all be similar to each other. Thus, similar triangles are triangles that have the same shape, but not necessa ...

Making Squares
... When I made the square using the three smaller triangles I noticed that the two smallest triangles are equal to one of the bigger triangle (they are congruent). That makes sense because the smaller triangles each have an area of ½ and ½ + ½ = 1 which is the area of the bigger triangle The two sm ...
