Question

MEDAL!!!

Answer 1

Figure ABCD is a parallelogram with point C (3, -2). What rule would rotate the figure 90 degrees counterclockwise, and what coordinate would be the output for point C'?

Possible answers:

(x, y) → (-y, -x); C' (2, -3)
(x, y) → (y, -x); C' (-2, -3)
(x, y) → (y, x); C' (-2, 3)
(x, y) → (-y, x); C' (2, 3)

Answer 2

Can you clarify the question marks.

Answer 3

Sorry, Thats what my laptop did... Its not supposed to mean anything... ignore it...

Answer 4

Okay, let me think.

Answer 5

The formula would be: (x, y) goes to (y, -x). So:
Now, due to how y is already negative that means if you were to rotate it 90 degrees it should be (3, 2) or (2, 3), but it could also be (-2, -3)
Based off of the answer I would say B: (y, -x) (-2, -3)

Answer 7

Alright.

Answer 8

If quadrilateral ABCD is congruent to quadrilateral EFGH, then what corresponding side is congruent to side FG?

Possible answers:

Side AB
Side BC
Side CD
Side DA

Answer 9

Well, a picture would greatly help, but I would assume it would be:
B. Side BC - But, you should attempt to show me the quadrilaterals.

Answer 10

I got the first question wrong and the second one correct!
Thanks for helpin. @Ghostgate

Answer 11

Dang, sorry I didn't give you the right answer for the first one. I'm guessing it was D I bet.
