Question

Figure ABCD is a parallelogram with point C (−4, 1). Figure ABCD is rotated 90° clockwise to form figure A′B′C′D′. What coordinate would be the output for point C'?

C' (1, 4)
C' (1, −4)
C' (−1, −4)
C' (−1, 4)

Answer 1

i think the answer is C. Not 100% sure though

Answer 7

now back to this new question lol its really later where i am so

Answer 8

Figure ABCD is a parallelogram with point C (−4, 1). Figure ABCD is rotated 90° clockwise to form figure A′B′C′D′. What coordinate would be the output for point C'?

C' (1, 4)
C' (1, −4)
C' (−1, −4)
C' (−1, 4)

Answer 9

i think its C not 100% sure tho

Answer 10

what do u think

Answer 11

Pick you case!

Apply the rule of rotation on the point C to get the output point C'

Answer 12

yes i went through it i think its -1, -4 what u mean?

Answer 13

Rule for 90 degree clockwise rotations

(x,y) ----> (y,-x)

the x and y coordinates swap. The second coordinate changes in sign after the swap

based on that table @3mar posted, it's the same as 270 degree counter-clockwise rotation

Answer 14

\[\Huge (x,y)\rightarrow (y,-x)\]
\[\huge (-4,1)\rightarrow(90~degree~cw)\rightarrow (1,4)\]

Answer 15

That is better that the previous...

Answer 16

Are you persuaded? @JULYAHX1

Answer 17

so the answer is .. A? not c? You guys SURE?

Answer 18

(1,4) is correct

Answer 19

ok well thanks for correcting me guys! phew
