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.
-
It's a push in the right direction for the OP.
-
similar to this one: ABC and AED are similar maybe you have assumed something about the diagram that you should not have... hopefully...
-
No. Not always the same. Therein lies your assumption.
-
What is "SF" ? I suppose may be Scale Factor ? The given figure may be fooling you into assuming more than what is stated.
-
These are similar with even three equal angles, but do not have parallel lines.

paulb203 replied to the thread Geometry: Similar Shapes.Thanks. Can similar shapes be equal in side lengths and angles; basically the same , except for how they are positioned?
-
paulb203 replied to the thread Geometry: Similar Shapes.Back to basics. Are the two triangles they are referring to as follows; ABE, the small triangle, bottom left? And, ACD, the large...

paulb203 replied to the thread Geometry: Similar Shapes.Thanks, guys. Loads for me to think about; I'll get back to this shortly. For now; yes, by (SF) I mean Scale Factor. Sorry about that.

paulb203 replied to the thread Geometry: Similar Shapes.Thanks. I wasn't until now, as I didn't think it was relevant, but you've got me thinking about it. My guess is the relationship is...

Are you assuming anything about how side CD is related to side EB ?
-
Why are there two possible values of x? Here's what I've done so far. AE(SF)=AD 12(SF)=15 SF=15/12 =5/4 AB(SF)=AC 8(5/4)=AC AC=10...
