Which transformations could be performed to show that
aabc is similar to aa"b"c"?
o
a reflection over the x-axis, then a dilation by a scale
factor of 3
a reflection over the x-axis, then a dilation by a scale
factor of
a 180° rotation about the origin, then a dilation by a
scale factor of 3
a 180° rotation about the origin, then a dilation by a
scale factor of

option d.

step-by-step explanation:

if two triangles δabc and δa'b'c' are similar then we take point c of δabc to find the transformation performed form c to c'.

coordinates of c are (0, 3) and the coordinates of c' are (0, -1).

this shows that c is rotated 180° about origin to get the new coordinates as (0, -3) and then new coordinates were dilated by 1/3 which forms c' as (0, -1)

therefore option d is the correct option.
