Use Midpoint and Distance Formulas

2. Terms
Midpoint of a segment is the point that divides the segment into two congruent segments

3. Segment bisector is a point, ray, line, line segment, or plane that intersects the segment at its midpoint

4. Examples
Open book to page 19.
3, 11

5. Midpoint Formula
To find the midpoint, (an (x, y) point) add up the x’s and divide by 2, add up the y’s and divide by 2

6. Examples
Find the coordinates of the midpoint of the segment with the given endpoints
(3, 5) and (7, 13)
(-8, -7) and (1, 5)

7. Distance Formula
To find the distance between the two points, use the distance formula

8. Examples Find the length of the 2 segments AB A(0, 2) B(-3, 8)
DC C(-2, 2) D(0, -4)
