Part A
Which describes a possible sequence of transformations that transforms polygon GHJK into polygon G'H' J'K"?
a 180-degree rotation about the origin, followed by a dilation centered at the origin with a scale factor of
a reflection across the line y = , followed by a dilation centered at the origin with a scale factor of 2.
a reflection across the y-axis, followed by a reflection across the 3-axis, followed by a dilation centered at the origin
with a scale factor of 2
a reflection across the y-axis, followed by a translation down 10 units, followed by a dilation centered at the origin with
a scale factor of

Part B
Which best describes the relationship between polygon GHJK and polygon G'#')'K'?
They are similar because polygon G'H' J'K' can be obtained from polygon GHJK by a sequence of transformations.
They are similar because the area of polygon GHJK is the same as area of polygon G'H'J'K'.
They are NOT similar because polygon G'H' 'K' cannot be obtained from polygon GHJK in a single transformation.
They are NOT similar because the orientation of polygon GHIK is not the same as the orientation of polygon G'H'J'K'.
