Question

Trapezoid PQRS is similar to trapezoid PꞌꞌQꞌꞌRꞌꞌSꞌꞌ.
Which transformations were performed on trapezoid PQRS to form trapezoid PꞌꞌQꞌꞌRꞌꞌSꞌꞌ? All dilations have a center of dilation at the origin and all rotations are around the origin.
A.PQRS was reflected across the y-axis and then dilated by a scale factor of 4 to form PꞌꞌQꞌꞌRꞌꞌSꞌꞌ.

B.PQRS was dilated by a scale factor of and then rotated 180° clockwise to form PꞌꞌQꞌꞌRꞌꞌSꞌꞌ.

C.PQRS was dilated by a scale factor of and then translated 2 units right and 2 units down to form PꞌꞌQꞌꞌRꞌꞌSꞌꞌ.

D.PQRS was dilated by a scale

Answer 2

@rational @GretaKnows

Answer 3

the scale factor is -1/4 because if you use the coordinates of the pre-image, you multiply them by -1/4 to get the image coordinates.

Answer 4

soo? a b c or d

Answer 5

its b or c actually!

Answer 6

B.
PQRS was dilated by a scale factor of and then rotated 180° clockwise to form PꞌꞌQꞌꞌRꞌꞌSꞌꞌ.

C.
PQRS was dilated by a scale factor of and then translated 2 units right and 2 units down to form PꞌꞌQꞌꞌRꞌꞌSꞌꞌ.

Answer 7

what is the scale facot on b and c? its not showing it

Answer 8

both of those say 1/4 in them

Answer 9

factor*

Answer 10

1/4

Answer 11

@tylermcmullen23 b and c both scale factors are 1/4

Answer 12

ok, try b. i hope its right, it would make more sense

Answer 13

thank you i have a few mor ei fyou wanna help?

Answer 14

B. is the right answer to anybody that saerches for this answer (:
