ObjectivesObjectives:•Bisect a segment.•Use the Midpoint Formula•Use the Distance Formula
Midpoint•The point that bisects a segment.•Bisects?splits into 2 equal piecesAMB12x+310x+512x+3=10x+52x=2x=1
Always Remember!Always Remember!•If they are congruent, then settheir measures equal to eachother!•Look for the “hatch marks” onthe figures to identify congruentparts.
Segment Bisector•A segment, ray, line, or plane thatintersects a segment at its midpoint.ABMk
Compass & Straightedge•These simple tools can be used to find themidpoint and to construct other importantpoints.•We actually don’t NEED a ruler (or a protractorif we’re creating a special angle); justsomething to draw straight lines with, and acompass will do!•l
Midpoint Formula•Used for finding the coordinates of themidpoint of a segment in a coordinateplane.
