Chapter 1 Section 3
Midpoint and Distance

2. Objective
You will learn to find segment lengths using midpoints and segment bisectors,
… Use the Midpoint Formula,
… Use the Distance Formula.

3. Vocabulary
Midpoint
Midpoint is the point that divides a segment into two congruent segments. S T
The segment bisector is a point, ray, line, line segment, or plane that intersects the segment at its midpoint.
Segment Bisector S T
Have students identify the congruent segments and the point, ray, line, line segment, and a plane the intersects at the midpoint of the segment.

4. The coordinate of the Midpoint.
Midpoint Formula
Use the extra spaces for sample problems. Include a segment with algebraic congruent segments.

5. Postulates
The distance between any two points.
Distance Formula
Have students you call on label the points and then have others label the geometric figures.
