The Two Coordinates of the Midpoint Segment: The Midpoint Rule

This video tutorial explains how to find the midpoint of a line segment. It begins with an introduction to the concept and provides examples of calculating midpoints for lines parallel to the X and Y axes. The video then derives the general formula for finding the midpoint of any line segment. Finally, it concludes with a challenge question to apply the learned concepts.

What is the X-coordinate of the midpoint for a line segment with endpoints at (2, 4) and (6, 4)?

• 2

• 4

• 8

• 6

If a line segment is parallel to the Y-axis with endpoints at (2, 2) and (2, 6), what is the Y-coordinate of the midpoint?

• 2

• 5

• 3

• 4

For a line segment with endpoints at (1, 2) and (5, 6), what are the coordinates of the midpoint?

• (3, 5)

• (2, 3)

• (4, 5)

• (3, 4)

Which formula correctly represents the X-coordinate of the midpoint for points (X1, Y1) and (X2, Y2)?

• (X1 + X2) / 2

• Y1 + Y2

• (Y1 + Y2) / 2

• X1 + X2

How can the midpoint rule be applied to divide an object into three equal parts?

• By using the midpoint formula twice

• By calculating the average of three points

• By dividing the line segment into three sections

• By finding two midpoints
