In the image below, a student designed two triangles for their coordinate cartoon drawing of a cat. The larger triangle was created to represent an ear and the smaller one was created to represent the cat’s nose. Are the two triangles shown similar? If so, what transformation was used to create the smaller triangle? If they are similar, what corresponding parts are congruent and which parts are proportional? If the triangles are not similar, explain why not. Make sure to provide evidence and explain your answer using complete sentences.

@JoannaBlackwelder do you think you can help?

joannablackwelder · Answer

I can try. IT looks like to me that the two triangles are similar.

anonymous · Answer

Yeah thats what I thought. They all have the same slope

joannablackwelder · Answer

Yup, and the corresponding side lengths have exactly a 2:1 ratio.

anonymous · Answer

Yeah that what I got(: Now its a reflection right?

anonymous · Answer

or is it a reflection and rotation?

joannablackwelder · Answer

Corresponding angles would be congruent.

joannablackwelder · Answer

The transformation part is not my strongest suit.

anonymous · Answer

Oh okay. and the third question. It would be corresponding angles and proportionate sides right?

joannablackwelder · Answer

Congruent angles and proportionate side.

anonymous · Answer

Okay thank you!

joannablackwelder · Answer

No worries :)

joannablackwelder · Answer

It seems like a reflection, but with the rescaling, not sure.
