All right, in your question, you're told that abcd is similar to f, e, h, g, and we're trying to find x.
00:09
Okay, so what we want to do is understand in similar figures, corresponding sides are proportional in their lengths.
00:17
So i'm going to start with the x, and i'm going to say x is over.
00:21
Now, x came from the segment cd.
00:24
So we can actually use the name.
00:27
Cd should match with hg.
00:30
So that is an 8 .5.
00:34
Using the name to help understand what corresponding parts are is a lot easier than understanding some of the flips and rotations that may have occurred in the two shapes.
00:45
Now we just need to pick another set of corresponding sides.
00:49
The only key here is, since i put x on top, i have to put something from this shape on top.
00:55
I'm going to choose ab or 16...
