A line segment is a part of a line that has two distinct endpoints. A line is a set of points that continue to infinity in both directions, so the endpoints of a line segment mark the start and end of the line segment. Common Core Geometry homework typically involves finding the length of a line segment, and the distance between two points.

## Length of a Line Segment

To find the length of a line segment, you need to use the distance formula. The distance formula is used to calculate the distance between two points, and the length of a line segment is just the distance between its two endpoints. The distance formula is written as d = √((x2 – x1)2 + (y2 – y1)2). To use the distance formula, you need the coordinates of both endpoints. Once you have the coordinates, plug them into the distance formula to calculate the length of the line segment.

## Distance Between Two Points

The distance between two points can also be found using the distance formula. To use the distance formula, you need the coordinates of both points. Once you have the coordinates, plug them into the distance formula to calculate the distance between the two points. The distance formula is written as d = √((x2 – x1)2 + (y2 – y1)2).

## Applications of the Distance Formula

The distance formula can be used to find the length of a line segment, and the distance between two points. It can also be used to find the midpoint between two points. The midpoint of a line segment is the point halfway between the two endpoints. To find the midpoint of a line segment, you need the coordinates of both endpoints. Once you have the coordinates, plug them into the distance formula to calculate the midpoint.

## Examples of Common Core Geometry Homework

Common Core Geometry homework typically involves finding the length of a line segment, and the distance between two points. It may also involve finding the midpoint between two points. Examples of Common Core Geometry homework include: finding the length of a line segment given the coordinates of its endpoints; finding the distance between two points given their coordinates; and finding the midpoint between two points given their coordinates.

Points, distance, and line segments are all important topics in Common Core Geometry. To find the length of a line segment or the distance between two points, you need to use the distance formula. The distance formula can also be used to find the midpoint between two points. Common Core Geometry homework typically involves finding the length of a line segment, and the distance between two points.
