Question

MEDAAL AND FAN, PROMISE
Match the pre-image, and its clockwise rotation, with the coordinates of its image.


1. (5, 2); 90° (-2, -5)
2. (5, 2); 180° (2, -5)
3. (5, 2); 270° (-2, 5)
4. (-5, 2); 90° (5, 2)
5. (-5, 2); 180° (-5, -2)
6. (-5, 2); 270° (2, 5)
7. (-2, 5); 90° (-5, 2)
8. (5, -2); 180° (5, -2)

Answer 1

rotation 90 degrees = (x,y) -> (y,-x)
rotation 180 " = (x,y) - > (-x,-y)
rotation 270 " = (x,y) -> (-y,x)

Answer 2

can you take it from there

Answer 3

srrry can u explain me better? just start this subject

Answer 4

ok rotation 90 degrees (x,y) you have (5,2) then convert to (y,-x) it would be (2,-5)

Answer 5

right

Answer 6

so i'll just change the positive and negative sign?

Answer 7

the next example rotation 180 degrees you have for (x,y) = (5,2)
you need to change as (-x,-y) so it would be (-5,-2)

Answer 8

then (2,5) correct?

Answer 9

@ivettef365

Answer 10

the answer for no. 2 (5,2) would be (-5,-2)
