Use Midpoint and Distance Formulas Geometry Section 1.3 Use Midpoint and Distance Formulas

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

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

Examples Open book to page 19. 3, 11

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

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

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

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