In this lesson we are going to learn about midpoints and segment congruence. First we'll define the midpoint, which is the point between the two given points. Midpoint M of PQ is the point right between P and Q, such that PM = MQ; that means PM is equal to MQ. You can think of it as the middle point. You'll learn the formulas for the midpoint, so when you are given two points, you can always find their midpoint. If a segment, line, or plane intersects a segment at its midpoint, it is called a segment bisector. It bisects the segment, i.e. it cuts it in half. This lesson also covers some very important theorems and their proofs.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
