This document provides examples and explanations of the midpoint and distance formulas, as well as transformations in the coordinate plane. It includes 4 examples of using the midpoint and distance formulas to find midpoints and lengths of line segments. It also discusses the different types of transformations - translations, reflections, rotations, and dilations - and provides examples of identifying each type of transformation using arrow notation. The homework assignments are to complete practice problems from sections 1.6 and 1.7 in the textbook, as listed.

Example 2:  Finding Midpoints What about if we were given a midpoint  and an endpoint?  How could we find the  missing endpoint? C ( 2, 2) M (4, ‐3) What are the coordinates of the  other endpoint D? 3
Example 3:  Finding the Length of a Segment What is            ? Method 1:   K B Use the Pythagorean Theorem to find the length of the hypotenuse 4
