Question

Sorry you can’t see the photo clearly, I know it’s a reduction but what is the scale factor?

Answer 1

1/2

Explanation:

Triangle XYZ has endpoints (0,0) (0,8) and (4,6)

Triangle X'Y'Z' has endpoints (0,0) (0,4) and (2,3)

As you can see, all the coordinates from Triangle XYZ are halved to get the coordinates of Triangle X'Y'Z', so the scale factor is 1/2.
