I am suppose to determine if the triangles are similar and why. I answered:
The two triangles pictured are similar because they are both right triangles (with one 90° angle), they both have side equivalent to one another but are under a different scale ratio.

I know there is more to this. Any suggestions? Thanks!

What is the definition of "similar"? It sounds more professional if you refer to the definition.
 
Similar would be considered a resemblance in appearance, character, or quantity, but not identical.These triangles appear to have the same shape, with the same angles and proportions. However, they are pictured in different size scales.
 
Sorry, correction, that is suppose to be a 12, not a 13. Does that make more sense? :))

That appears to be a generic dictionary defintiion. Do you have a technical mathematical difinition?
 
You keep referring to mathematical definition. I am not sure what you are looking for.
Are you refering to the words congruent (segments and angles) and rep-tile ( a figure used to make a larger similar figure)? :(
