What is a similarity statement and how do I write one?
I learned about them in geometry the other day, but i still don't understand them.....

Best ResponseYou've already chosen the best response.3a good example of "similar" in geometry is a square. two squares of different sizes are similar (they have the same shape, and their sides form identical angles)

Best ResponseYou've already chosen the best response.3if two shapes are similar, then if you change the size you can make them look identical.

Best ResponseYou've already chosen the best response.0stating something like they have the same angles

Best ResponseYou've already chosen the best response.3similar is useful when you have triangles. Here is an example: dw:1436992086041:dw

Best ResponseYou've already chosen the best response.3the two triangles have the same shape, but different sizes. but say you know the height of the person, and measure his shadow then you measure the length of the tree's shadow. because the triangles are similar , we can figure out how high the tree is!

Best ResponseYou've already chosen the best response.3the "similarity statement" could be written: person's height: his shadow :: tree's height: tree shadow or using fractions \[ \frac{person\ height}{his \ shadow} = \frac{tree\ height}{its \ shadow} \]

Best ResponseYou've already chosen the best response.3though in geometry, we usually use letters to name the sides of a triangle.

Best ResponseYou've already chosen the best response.0Sorry, but @phi, what is a similarity statement?

phi

Best ResponseYou've already chosen the best response.3a similarity statement tells you which sides "go with" which side. for example, suppose we have these two triangles dw:1436992841773:dw

phi

Best ResponseYou've already chosen the best response.3the angle at A "matches" the angle at Y B with Z C with X we could write ABC is similar to YZX (in fact people would usually label the 2nd triangle so it reads XYZ, to make it clearer)

phi

Best ResponseYou've already chosen the best response.3I think they use ~ instead of = so you would write ABC ~ YZX and that is short to say: angle A matches angle Y angle B matches angle Z angle C matches angle X it also says: side AB is similar to side YZ (the side from angle A to angle B) matches the side from Y to Z and side BC ~ side ZX

Best ResponseYou've already chosen the best response.0@phi, Thank you. On my homework though sometimes I didn't see them corresponding in the choices. Like how you had ABC similar to YZX..... Or maybe I just didn't see it right...

Best ResponseYou've already chosen the best response.3Post a specific question and choices, and maybe we can make sense of it.
