Midpoint Vocabulary

What is the definition of midpoint?

• The point that divides a line segment into four equal parts.

• The point that divides a line segment into two unequal parts.

• The point that divides a line segment into three equal parts.

• The point that divides a line segment into two equal parts.

What is the formula for finding the midpoint?

• (x1 + x2, y1 + y2)

• ((x1 + x2) / 2, (y1 + y2) / 2)

• ((x1 + x2) / 2, (y1 + y2) / 2)

• (x1 - x2, y1 - y2)

Solve for the midpoint given the coordinates (2, 4) and (6, 8).

• (4, 6)

• (7, 9)

• (5, 7)

• (3, 5)

Find the midpoint of the line segment with endpoints (1, -3) and (5, 7).

• (3, 2)

• (2, 4)

• (4, 2)

• (0, 0)

True or False: The midpoint of a line segment divides it into two equal parts.

• True

• False

• Sometimes

• Depends on the length of the line segment

Calculate the midpoint of the line segment with endpoints (-2, 1, 3) and (4, -5, 7).

• (1, -2, 5)

• (0, -1, 4)

• (2, -3, 6)

• (-3, 0, 4)

If the midpoint of a line segment is (3, -2), and one endpoint is (1, 4), what are the coordinates of the other endpoint?

• (4, -8)

• (2, 2)

• (1.5, 1)

• (5, -6)

What is the midpoint of the line segment with endpoints (-3, 0) and (0, 6)?

• (0, 3)

• (-2, 3)

• (-1.5, 3)

• (-1.5, 6)

Explain how to find the midpoint of a line segment using the midpoint formula.

• The midpoint of a line segment can be found by subtracting the x-coordinates and the y-coordinates of the endpoints.

• The midpoint of a line segment can be found by multiplying the x-coordinates and the y-coordinates of the endpoints.

• The midpoint of a line segment can be found by taking the maximum of the x-coordinates and the maximum of the y-coordinates of the endpoints.

• The midpoint of a line segment can be found by taking the average of the x-coordinates and the average of the y-coordinates of the endpoints.
