 The image of ΔABC is ΔA′B′C′. How do the​ x coordinates of the vertices​ change? How do the​ y coordinates of the vertices​ change?

• The​ x-coordinates of the vertices are the same distance away from the​ y-axis but in the opposite direction.

• The​ x-coordinates of the vertices are the same distance away from the​ x-axis but in the opposite direction.

• The​ x-coordinates of the vertices change differently depending on where they are on the figure..

• The​ x-coordinates of the vertices are unchanged in the image.

Is Δ​X'Y'Z' a rotation of Δ​XYZ? Explain.

• No. While the​ size, shape, and orientation are the​ same, the transformation used was a translation.

• Yes. The​ size, and shape are the same. Rays connecting the origin with corresponding points show an angle of rotation of 90° counterclockwise about the origin.

• No. While the​ size, shape, and orientation are the​ same, the transformation used was a reflection.

• No. The​ size, shape, and orientation of each triangle are not all the same.
