Lesson 3: Distance and Midpoint Chapter 1: Tools of Geometry
Midpoint- the point on a segment that divides the segment into two congruent segments • Segment bisector- any line, segment or plane that intersects a segment at its midpoint Definitions
Midpoint Formula- used to find the point half way down a segment ex: Find the midpoint of JK if J(-1,2) and K(6, 1) * on a number line- add the endpoint values and divide by 2 • Distance Formula- used to find the length of a segment. ex: Find the distance between A (5,1) and B (-3, -3). *on a number line- subtract the endpoint values Distance and Midpoint
Use the number line to find the midpoint and the measure of AX. examples
