Question

A triangle undergoes a sequence of transformations. First, the triangle is dilated by a scale factor of 1/3 about the origin. Then the triangle is reflected over the x-axis. Finally, the triangle is translated left 3 units and up 2 units.How does the image triangle compare to the pre-image triangle? Explain.

Answer 1

Since there was a dilation, the two triangles will be similar. The scale factor is less than one and is a reduction, therefore, the image will be smaller than the pre-image.

Answer 2

Because there was a dilation, the two triangles will be similar. The scale factor was less than one, so the image will be smaller than the pre-image.
