In this lesson our instructor talks about midpoints and segment congruence. She talk about the definition of midpoint and the midpoint formulas. She discusses midpoint on a number line and coordinate plane. She talks about the segment bisector. She then talks about the midpoint theorem and does a proof on it. Four complete extra example videos round up this lesson.
The midpoint M of PQ is the point between P and Q such that PM = MQ
On a number line, the coordinates of the midpoint of a segment whose endpoints have coordinates a and b is
In a coordinate plane, the coordinates of the midpoint of a segment whose endpoints have coordinates (x1, y1) and (x2, y2) are
