Transformation Review #2 no simfigs or dimensions

Front

Quadrilateral A, B, C, D is transformed according to the rule (x,y)-- (x - 2, y +4) to create quadrilateral A'B'C'D'. Which statement is true?

Back

The angle measures of A'B'C'D' are congruent to the angle measures of ABCD.

Front

Which statement describes the mapping? Options: The mapping represents y as a function of x, because each y-value corresponds to exactly one x-value. The mapping does not represent y as a function of x, because two of the x-values correspond to the same y-value. The mapping represents y as a function of x, because each x-value corresponds to exactly one y-value. The mapping does not represent y as a function of x, because there are more x-values than different y-values.

Back

The mapping represents y as a function of x, because each x-value corresponds to exactly one y-value.

Triangle ABC is dilated with the origin as the center of dilation using the rule (x,y) -- (4x, 4y). Which statement is true of triangle A'B'C'?

Back

Triangle A'B'C' is larger than triangle ABC because the scale factor is greater than one.
