Question

Triangle ABC is dilated to create triangle DEF on a coordinate grid. You are given that angle A is congruent to angle D. What other information is required to prove that the two triangles are similar? (1 point)
Question 12 options:
1) Angle B is congruent to angle D.
2) Segments AB and DE are congruent.
3) Angle B is congruent to angle E.
4) Segment AC is congruent to segment DF and segment BC is congruent to segment EF.

Answer 1

@phi @iGreen

Answer 2

What do you think?

If we know that one more angle is congruent to a different angle, we can prove that they are similar.

Answer 3

igreen we missed something

Answer 4

on mine

Answer 5

@iGreen honestly im not sure, i just know that when you dilate something its that its shrunk or enlarged, but i don't know what information you need to know when it comes to proving that the two triangles are similar

Answer 6

We just need another pair of congruent angles, so B and D are out since they don't mention angles, what do you think?

Answer 7

@iGreen so it'd be a?

Answer 8

wooooops i meant c

Answer 9

Yes, you are correct!

Answer 10

@iGreen thanks so much!!

Answer 11

No problem, sorry for the delay.
