Figure efgh on the grid below represents a trapezoidal plate at its starting position on a rotating surface.

The plate is rotated 90° about the origin in the counterclockwise direction. in the image trapezoid, what are the coordinates of the endpoints of the side congruent to side gh?

i saw the grid.

point e (-4,8)
point f (-7,5)
point g (-4,3)
point h (-2,5)

to get the new coordinate of each point for a 90° clock-wise rotation,
(x,y) becomes (-y,x)

point g (-4,3) becomes (-3,-4)
point h (-2,5) becomes (-5,-2)

select one:
a. (-8, -4) and (-5, -2)
b. (4, -8) and (2, -5)
c. (-3, -4) and (-5, -2)   correct answer
d. (4, -3) and (2, -5)

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
