Finding Midpoint in the Coordinate Plane

This is an example of

• Coordinate points

• Distance Formula

• X and Y

• Midpoint Formula

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 point that divides, or bisects, a segment into two congruent segments is called a ___________________.

• midpoint

• congruent segment

• angle bisector

• endpoint

The midpoint formula give the answer in a form of:

• a number (value)

• a coordinate (x, y)

What is the formula for finding the midpoint?

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

• Equidistant

• Congruent

• Regular

• Equilateral

Divides the segment into two congruent segments. (Select all that apply)

• Midpoint

• Segment bisector

Answer explanation

$\left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\right)$ Midpoint Formula
