Question

Which is the location of S' when trapezoid RSTU is rotated 90° clockwise about the origin to produce trapezoid R'S'T'U? Explain.

Answer 1

Answer:

D. (12,3)​

Step-by-step explanation:

From the graphical diagram attached below ; we would realize that the x-coordinate is in the positive direction and the y-coordinate is in the negative direction.

Initially, the location of S = 12 to the horizontal x axis from the graphical diagram.  So, if the trapezoid RSTU is rotated 90° clockwise about the origin to produce trapezoid R'S'T'U, we will have :

S' = 3

Thus; the (x,y) coordinate of  R'S'T'U = (12,3)​
