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...

You got it. -

Yeah, when you introduce friction you add some more “internal energy tanks” for the system and its surroundings i.e. the mass in the...

I’m working my way through Khan Academy’s High School Physics and I want to check that I’m getting the concept of conservation of...
