I dislike problems like this where the figure is maliciously drawn way out of scale. -
You haven't got yourself in a muddle, it is a trick question and you are in a muddle because you haven't spotted the trick. I'm not...

They are. Not necessarily... How could this possibly be? Here is a pair of similar triangles:
-
Similar only means that the angles are the same, not the size. If, e.g., two angles are equal, then we can have the situation as the...
-
Yes, and as already noted, if both the corresponding sides and angles are equal, the two figures are congruent.

Do CD and BE have to be parallel? Look at what I posted previously, #7, where both triangles are similar. What do you notice about sides...

paulb203 replied to the thread Geometry: Similar Shapes.Thanks, Steve. I'll give this a go after I've revisited the very basics; I fear I've got myself in a right muddle :)

@paulb203, if you are still struggling, you have probably hit a bit of a mental block. Here’s an extra problem to try which should...

Oh I didn't understand that it was rhetorical... my bad

paulb203 replied to the thread Geometry: Similar Shapes.Thanks. I thought they had to be parallel in order for the triangles to be similar (?).

No. Renormalize's post is rhetorical. He is drawing attention to the fact that it's Mark44 who is the one making the same assumption as...

Your equation has the unique solution ##x=2##. So why does the original problem in post #1 state: ?
-
Yes, what is "SF"? Two triangles are said to be similar if their corresponding angles are equal. In similar triangles, the...

What does this figure have to do with the given problem?

I'll DM you, so I don't give the answer away to the OP.
