B.
Trapezoid A is neither similar nor congruent to Trapezoid B.
C.
Trapezoid A is similar to Trapezoid B by dilating Trapezoid A at point (-2,5) by a scale factor of 2 and reflecting it across the x-axis.

Answer 1

@Mehek14

Answer 2

different sizes so not congruent for sure


D is out for sure

Answer 3

what's the scale factor for A?

Answer 4

um not sure how to find that

Answer 5

no in the answer choice

Answer 6

it's not there

Answer 7

oh sorry 1/2 is what it says

Answer 8

not A because dilating by 1/2 makes it smaller, not bigger

Answer 9

so C?

Answer 10

Yes

Answer 11

okay thank you @FaiqRaees .. what is your thought @Mehek14 ?

Answer 12

correct

Answer 13

D ruled out: Not congruent
A ruled out: Scale factor not 0.5
B ruled out: It is similar
C chosen: Scale factor is 2

Answer 14

thank you both so much!

Answer 15
