Are the two triangles congruent?

Check all that apply

Relationship between the sides?

Divide the corresponding lengths: What do you always get? Why does this make sense?

Are the two triangles above congruent? Explain in detail why or why not? Are the angles congruent? Are the sides congruent?

Relationship between the sides?

Divide the corresponding lengths: What do you notice?

**Spoiler** The two triangles above are not congruent....they are however similar. This is why I didn't like when you used "similar" or "same shape" to describe congruency. Finish this sentence: Two triangles are similar when the angles are ______________________________ and the sides ________________________________
