Question

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 EH?

(8, 4) and (5, 2)

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

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

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

Answer 1

rotate 90 :-

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

Answer 2

have a look at pic,
can u tell the coordinates of H ?

Answer 3

(-2, 5)

Answer 4

good :)
apply the transformation : rotate 90

Answer 5

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

(-2, 5) --> ?

Answer 6

(-5, 2)?

Answer 7

careful

Answer 8

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

(-2, 5) --> (-5, -2)

Answer 9

look at ur options,
you got lucky, oly one has (-5, -2)

Answer 10

ok, can you help me with this one?

What will be the location of T' in the image Trapezoid S'T'U'V'?

(12, 6)

(12, 7)

(16, 7)

(16, 6)

Answer 11

is that the complete question ?

Answer 12

it doesnt say, wat transformation to apply to trap STUV :o

Answer 13

woops.
Rectangle J'K'L'M' shown on the grid is the image of Rectangle JKLM after transformation. The same transformation will be applied on Trapezoid STUV.

Answer 14

have a look at pic,
can u tell me coordinates of M
can u tell me coordinates of M'
