Find the coordinates of triangle ABC A(2,1) B(3,0) C(1,-2) after a dilation with a scale factor of 3

Remember the key word”factor” which means to multiply. Multiple all those numbers by 3!

Step-by-step explanation:I’m going to do 2 of them and you can do the last one (2,1)x3= the dilation (6,3). (3,0)x 3 gives the dilation (9,0). (1,-2)x3 gives the dilation of (3,-6). See it’s very easy.

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32

6-3=3

3*3=9

9+12=21

21/3=7

7*8=56

56 is your answer
