Question

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 EF?

(-8, -4) and (-5, -7)

(-8, -4) and (-5, -2)

(4, -8) and (2, -5)

(4, -8) and (7, -5)

Answer 1

the answer is the first one: (-8, -4) and (-5, -7)

Answer 2

thanks but can you give me an idea of what you did?

Answer 3

well idk if its right but what i did was i lokked at the graph for a while, and then i looked at angle E and angle F, and tryed to locate their coordinates. that's when i got (-8, -4) and (-5, -7)

Answer 4

*looked

Answer 5

ok thanks, that works too xD

Answer 6

welcome
