If an image of a triangle is congruent to the pre image what is the scale factor of the dilation

Feb 06, 2019 · When the dilation made the pre-image smaller, the scale factor was _____ than one. Dilating a figure on the coordinate plane Graph PQR with vertices P (0, 2), Q (1, 0), and R (2, 2) and its image after a dilation with scale factor 3 and a center of dilation at point (0, 0). State the points of the image, and plot them.

Dilation is a slightly different monster. While the other transformations give us a congruent shape, dilation changes the size of the Given that the green triangle is the preimage, identify the scale factor used in this dilation to draw the image of the orange triangle.

2. When a triangle is dilated, the pre-image and the image are similar triangles. There are three cases of triangles being dilated: • The image is congruent to the pre-image (scale factor of 1). • The image is smaller than the pre-image (scale factor between 0 and 1). • The image is larger than the pre-image (scale factor greater than 1). 3.

Triangle ABC was rotated 900 clockwise. Then it underwent a dilation centered at the origin with a scale factor of 4. Triangle A'B'C' is the resulting image. What parts of AA'B'C' are congruent to the corresponding parts of the original triangle? Explain your reasoning. Compare the perimeters of AABC and AA'B'C'. Explain your reasoning.
