This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: The point in the \$x\$-\$y\$ plane with coordinates \$(1000,2012)\$ is reflected across the line \$y=2000\$. What are the coordinates of the reflected point?...

In this lesson, students know that dilations map circles to circles and ellipses to ellipses with the same shape. Students know that to shrink or magnify a dilated figure back to its original size from center O with scale factor r you must dilate the figure by a scale factor of 1/r.

This lesson unit is intended to help teachers assess how well students are able to: recognize and visualize transformations of 2D shapes; and translate, reflect and rotate shapes, and combine these transformations. It also aims to encourage discussion on some common misconceptions about transformations.

In this lesson, students learn the definition of dilation and why "same shape" is not good enough to say two figures are similar. Students know that dilations magnify and shrink figures.
