what is the definition of isometric?

anonymous · Answer

A transformation that shows you that an original figure and the image of it are congruent @amistre64

amistre64 · Answer

is the second setup have congruent triangles, or similar triangles?

anonymous · Answer

They'd be congruent right?! Because other than the one inside being smaller, they're the same! So it would be an isometry

amistre64 · Answer

congruent means "equal in every way" except for rotation.

amistre64 · Answer

similar refers to a scalable (sizable) property

anonymous · Answer

So the first one wouldn't be an isometry?

amistre64 · Answer

since the 2nd setup has different sizes, they are NOT confruent, and therefore NOT isometric

the 1st setup is fine
