This video tutorial by Mr. Backberg introduces the concept of the midpoint in geometry, explaining how it divides a segment into two congruent parts. The tutorial covers the use of algebraic expressions to find segment lengths and demonstrates the midpoint formula for determining the midpoint of a segment on a coordinate plane. It also includes examples of finding a missing endpoint using the midpoint formula.

What does the midpoint of a segment do?

• Changes the length of the segment

• Divides the segment into two unequal parts

• Divides the segment into two congruent segments

• Marks the end of the segment

What is the midpoint formula for a segment with endpoints (x1, y1) and (x2, y2)?

• ((x1 / x2) / 2, (y1 / y2) / 2)

• ((x1 * x2) / 2, (y1 * y2) / 2)

• ((x1 - x2) / 2, (y1 - y2) / 2)

• ((x1 + x2) / 2, (y1 + y2) / 2)
