Learning goals: Learning Goals Addressed • Apply dilations to figures using distance measurements. (Lesson 2) • Apply dilations to figures on a grid. (Lesson 3) • Understand that when two polygons are similar, their corresponding angles are all congruent and there is a single scale factor by which we can multiply all of the side lengths in one figure to get the corresponding side lengths in the other. (Lesson 6) • Show that all slope triangles on one line are similar and have the same slope. (Lesson 9) • Determine the slope of a line in a plane. (Lesson 9) • Explain whether a point is on a line by finding quotients of horizontal and vertical distances. (Lesson 10) Materials • Geometry toolkits
