DaveC426913 replied to the thread Geometry: Similar Shapes.In geometry, there are only three ways of determining that two lines are parallel: definition, postulate, and proof. Diagrams are not to... -
DaveC426913 replied to the thread Wood/Glass/Metal Doggie- lovers: what do dogs like? Ramp or step?.Yeah, we took her for some agility training a few years ago, where she learns to navigate an obstacle course, including ramps. Hopefully...

DaveC426913 replied to the thread Geometry: Similar Shapes.OK, but that's only one of the two indicated solutions. And you've based it on this assumption: $$\ AB:AE=AC:AD$$

it has so much more pizzazz than "guess", don't you think....?

Like.
Yes, e.g. post 7. -

And it is perfectly clear from the context and how the thread went on.

DaveC426913 replied to the thread B A question about warp bubbles and navigation.My concern stems from the opening line, which is: "I've been thinking about the concept of warp drive. From what I understand, when a...

DaveC426913 replied to the thread Geometry: Similar Shapes.Totally 110% agree. Engineering is a completely different animal. Absolutely. In engineering, two lines can be parallel if they are...

DaveC426913 replied to the thread Geometry: Similar Shapes.Do you mean could occur if all numbers were put to the diagram? Because we can't just pretend, say, that the triangles are isosceles...

DaveC426913 replied to the thread Geometry: Similar Shapes.Since the two triangles are defined as similar, there must be two possible solutions (since they share an angle in the diagram). If...

DaveC426913 replied to the thread Geometry: Similar Shapes.I've not encountered that notation. Where I come from, | means equal length. To-wit: AB and DC are parallel. AD and BC are of equal...

I am really surprised that some seriously expect to take BE and CD as parallels and don't have any problems taking 12 and 3 being...
