A.

R' (-4, 3), S' (3, 40), T' (28, 3)

B.

R' (-4, 3), S' (12, 10), T' (28, 3)

C.

R' (3, 7), S' (7, 14), T' (11, 7)

D.

R' (-4, 12), S' (12, 40), T' (28, 12

Answer 1

Afternoon @harliii, hope you're doing well today. How far have you gotten with this one?

Answer 2

not far

Answer 3

Do you know what it means for one triangle to be a dilation of another triangle?

Answer 4

ah

Answer 5

Have you tried plotting the points at least?

Answer 6

i cant on the site there is no graph

Answer 7

Hang on a minute.

Answer 8

https://www.geogebra.org/graphing?lang=en

Answer 9

You can use that to plot your triangles.

Answer 10

Technically, you don't need to graph it to figure out the answer but it's still nice to be able to have visuals of the problem.

Answer 11

well what is the answer

Answer 12

What is the answer? Don't you mean to ask, "How do I get TO the answer?".

Answer 13

That's what I was able to graph using Geogebra. If you notice, the coordinates of the larger triangle is 4 times that of the original triangle.

Answer 14

NO LIKE WHAT IS THE ANSWER CHOICE

Answer 15

When you post problems here, you are agreeing to get help with understanding how to do the problem, not get direct answers.

Answer 16

Y BC I DONT GET IT
