Question 2

Definition of Midpoint

Answer 2

If M is the midpoint of PQ, then M is the point between P and Q such that PM = MQ

Question 3

Segment Bisector

Answer 3

Any segment, line, or plane that intersects a segment at its midpoint

Question 4

Midpoint in the Coordinate Plane

Answer 4

The coordinates of the midpoint of a line segment whose endpoints have coordinates (x1, y1) and (x2,y2)
M = ((Sigmax)/2, (Sigmay)/2)

Question 5

Distance Formula

Answer 5

The distance, d, between any points with coordinates (x1,y1) and (x2, y2) is given by the following formula:
d = sqrt([Deltax] ^ 2 + [Deltay] ^ 2)
