Question

(04.02 HC)

Are the two figures below similar? Explain why or why not using complete sentences. Provide evidence to support your claims.

Answer 1

1) Are ALL the angles congruent?
2) Are ALL the corresponding parts proportional?

Answer 2

Well that's what I'm trying to figure out, i don't think the angles are congruent, but i don't know about the sides.

Answer 3

The sides don't matter if the angles are not congruent. You think the angles are not congruent or you can prove that they are not? Quite a big difference.

Answer 4

Calculate two slopes:

1) DE from the left-hand figure, and
2) JK from the right-hand figure.

Answer 5

the slope of DE is -2

Answer 6

the slope of JK is -1

Answer 7

so that means they are not similar right?

Answer 8

because the angles are not congruent?

Answer 9

Well thanks for your help Tkhunny. :)
