Question

please explane the answer and get medal

Answer 1

Figure ABCD is a trapezoid with point A (0, -4). What rule would rotate the figure 270° clockwise, and what coordinate would be the output for point A'?

Answer 2

(x,y)→(y,-x); A' (-4, 0)

(x,y)→(-y,x); A' (4, 0)

(x,y)→(y,x); A' (-4, 0)

(x,y)→(-y,-x); A' (4, 0)

Answer 3

thanks

Answer 4

i know

Answer 5

donti have to use the 180 rule or omeething

Answer 6

why not

Answer 7

ho said that i have given a answer before

Answer 8

is the answer (x,y)→(y,-x); A' (-4, 0)

Answer 9

ho is te admin

Answer 10

-4,0 is the results

lets see if the rule is good: (0,-4) -> (-4,0) cant tell with that zero in the way :/

Answer 11

id test it on a different point: 1,1 270s to 1,-1 ... thats better

Answer 12

lol, 0,4 seems simpler too

Answer 13

amistre, you have a valid point, the zero doesn't narrow it down

Answer 14

the correct answer was (x,y)→(-y,x); A' (4, 0)

Answer 15

oh gosh darn, i went counterclockwise

Answer 16

thanks for explaining it

Answer 17

if you go 90 counter clock 3 time then you get the correct answer

Answer 18

is that the answer?

Answer 19

because the rule for counter clock is -y,x

Answer 20

i think it is correct whn i sumit i will send message

Answer 21

bye

Answer 22

oh i see
clockwise 270 degrees = 90 counterclockwise degrees

Answer 23

and the rule for a clockwise rotation of 90 degrees is
(x,y) -> (-y,x)
