Question

Two similar triangles below 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 across the x-axis
Dilation by a scale factor of 2 followed by reflection across the x-axis
Dilation by a scale factor of 4 followed by reflection across the y-axis
Dilation by a scale factor of 2 followed by reflection across the y-axis

Answer 1

I will attach image

Answer 2

I think its the second one

Answer 3

see how the reflection is done on the X-axis, what doe that tell you?

Answer 4

Its either B or A

Answer 5

@jhonyy9

Answer 6

I think it is B because both x and y coordinates are dilated by a scale factor of 2. The sign of the y coordinate changes in the image

Answer 7

Correct :)

Answer 8

I want to if its right or not tho

Answer 9

its Right

Answer 10

you are right with B. sure
