Consider polygon abcd with coordinates a(8/12), b(10,4), c(4,4), d(2,8). what are the coordinates of a" b" c" d" if we reflect it over the line y=2, then dilate by a scale factor of 1/2 centered at the orgin?

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
