Question

1.Vertex B of trapezoid ABCD has coordinates (7, −2).If trapezoid ABCD is translated 3 units left, what are the coordinates of vertex Bʹ?

2.The coordinates of the vertices of ΔPQR are (–2, –2), (–6, –2), and (–6, –5).
The coordinates of the vertices of ΔPʹQʹRʹ are (−2, 2), (−6, 2), and (−6, 5).
This transformation can be expressed as (x, y) → (x, −y).

Is the orientation of ΔPQR the same as the orientation of ΔPʹQʹRʹ? Why or why not?

A.
No, ΔPʹQʹRʹ is a reflection of ΔPQR over the x-axis.

B.
Yes, ΔPʹQʹRʹ is a reflection of ΔPQR over the x-axis.

C.
Yes, ΔPʹ

Answer 3

3. A square has the coordinates (−2, 2), (−4, 2), (−4, 4), and (−2, 4) at its vertices. The transformed square has the coordinates (−6, 6), (−12, 6), (−12, 12), and (−6, 12) at its vertices.

Are the square and its transformation congruent? Why or why not?

A.
Yes, the transformation is a dilation of the square with a scale factor of 1/3 .

B.
Yes, the transformation is a dilation of the square with a scale factor of 3.

C.
No, the transformation is a dilation of the square with a scale factor of 3.

D.
No, the transformation is a dilation of the square with a scale factor of 1/3 .
