Use Midpoint and Distance Formulas 1.3 Geometry

Definition of Midpoint The midpoint of a segment is the point that divides the segment into two congruent segments. Midpoint formula If C is the midpoint of segment AB, then AB = CB.

Midpoint Formula The midpoint of line segment AB written is

Segment bisector A segment bisector is any point, line, line segment, ray, or plane that intersects a line segment to create two smaller line segments that have equal length. is a ray that cuts into two congruent segments and Therefore, is a segment bisector.

Distance Formula The distance between two points A(xA,yA) and B(xB,yB) is

Using the midpoint and distance formulas Given R(1,-3) and S(4,2) find midpoint of Find RS
