I'm having problems figuring which sides of similar triangles correspond to each other. I can check and find the lines that go through the same angles, but that only works when they are constructed by crossing the same lines and similar approaches.(adsbygoogle = window.adsbygoogle || []).push({});

If you have a right triangle however, and divide it with a line from the 90 degree angle and down to the hypothenuse, you now have 3 triangles which are all similar. And I have to stare at these for 20 minutes and make miniature drawings to figure out which side corresponds to which in the other.

So, I'm thinking that I am missing some basic approach here, but I'm doing self study from a book so I cant kidnap a teacher and make him show me.

Any tips, or recommended reading?
