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.

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.

A midpoint of a segment is a point that divides the segment into two __________________________ segments.

• Equidistant

• Congruent

• Regular

• Equilateral

Difference between two points and the absolute value of that difference.

• Distance

• Coordinate

• Axiom

Answer explanation
