1. A composition of transformations means performing one transformation and then applying another transformation to the image.
2. When reflecting a figure over the x-axis, the x-coordinate remains the same, and the y-coordinate becomes its .
3. A rotation of 180 degrees about the origin changes the coordinates (x, y) to .
1. Describe the steps to perform a translation of a point (x, y) by (a, b) followed by a reflection over the y-axis.
Consider triangle ABC with vertices A(1, 2), B(4, 2), and C(1, 5).
1. Plot triangle ABC on the coordinate plane below.
2. Perform a translation of triangle ABC by the rule (x+2, y-3) to get A'B'C'. Plot and label A'B'C'.
3. Now, reflect A'B'C' over the x-axis to get A''B''C''. Plot and label A''B''C''.
4. Write the coordinates of A'', B'', and C''.
A'' =
B'' =
C'' =
