Question

Triangle TUV was dialted. Com out the missing coordinates on your recording sheet, and determine the type of exhalation that occurred T(2, 4) T'(3, 6) U(4, 6) U'(___, ___) V(4, 8) V'(___, ___)A. By a scale factor of 1/3?B. By a scale factor of 2/3?C. By a scale factor of 3/2?D. By a scale factor of 2?

Answer 1

C) by a scale factor of 3/2

1) The pre-image is

T(2,4) U(4,6) V (4,8)

The image

T'(3,6) U' ( )

2)Let's find the scale factor by picking one point and then dividing each corresponding coordinates to check if what's the scale factor, in this Dilation about the origin.

Since we T and T' let's do it with this point.

Dividing the y coordinate of each we'll have

(3/2, 6/4)

3) So there was a dilation by a scale factor of 3/2
