Question

The composition ry-axisT(0, 2) is used to transform a triangle having a vertex at (0, 1). Describe how to find the coordinates of the image of this vertex.

Answer 1

Answer:

Sample Response: Perform the transformations from right to left. First, rotate the triangle 90 degrees. Negate the y-coordinate and then switch the coordinates to get (–1, 0). Next, perform the translation up by adding 0 to the x-coordinate and 2 to the y-coordinate to get (–1, 2). Finally, reflect this point over the y-axis by negating the x-coordinate to get (1, 2).
