Similar triangles

[charlie_eppes]

The one diagonal of a trapezoid separate the other in attitude attitude 2:3 and the middle interval of it is 5cm. Find its bases.

Have you ever heard of Thales???

[charlie_eppes]

Yes but when I applied it there are too many with x. I just begin this kind of problems and for me they are difficult. And why always someone answer to me with an answer instead of giving clear answer and that mean solution. I dont know how to handle with it and that's why i ask for help not criticisim.

You have to build one line parallel to the diagonal that is not separated to attitude 2:3.

From Tales' theorem we get that the the bigger base : smaller base = 3 : 2

Here is the exact definition of similar triangles-Triangles are similar if they have the same shape, but not necessarily the same size means the size can be different.
