Question

Two similar triangles are shown on the coordinate grid:

Which set of transformations has been performed on triangle ABC to form triangle A’B’C’


Dilation by a scale factor of 4 followed by reflection about the x-axis

Dilation by a scale factor of 2 followed by reflection about the x-axis

Dilation by a scale factor of 4 followed by reflection about the y-axis

Dilation by a scale factor of 2 followed by reflection about the y-axis

Answer 1

im going with c

Answer 4

what is the distance from (0,0) to point B?

Answer 5

2

Answer 6

you sure?

Answer 7

B not B'

Answer 8

1? im not good at comprehending math im sorry if I get it wrong.

Answer 9

start at point B

count how many spaces you move until you get to the origin

Answer 10

yes sorry I didn't see the 1

Answer 11

yes 1 unit from B to (0,0)

Answer 12

now how far is it from (0,0) to B'

Answer 13

lol 4?

Answer 14

(0,0) to (2,0) is 2 units, not 4

Answer 15

distance from the origin to B = 1

distance from the origin to B' = 2

Answer 16

so the scale factor is 2

A'B'C' is twice as far away from the origin as ABC is

Answer 17

So that means it will be a scale factor of 2 over the x-axis?

Answer 18

over the y axis (the vertical axis)

Answer 19

right while the x is the horizontal axis. thank you for giving me clarity and understanding!
