What is the Length of Line Segment MQ?
A line segment is a straight path connecting two distinct points in a plane. It is a fundamental geometric concept with various applications in mathematics and other fields.
Definition of Line Segment
Mathematically, a line segment PQ is defined as the set of all points that lie on the line passing through points P and Q. It is denoted as —PQ—.
Identifying Line Segment MQ
Given points M and Q with coordinates (x 1, y 1) and (x 2, y 2), respectively, the line segment MQ can be identified.
The distance formula to calculate the length of line segment MQ is:
Length of MQ = √[(x2
- x 1) 2+ (y 2
- y 1) 2]
Calculating the Length of MQ
Substituting the coordinates of M and Q into the distance formula:
Length of MQ = √[(x2
- x 1) 2+ (y 2
- y 1) 2]
Simplifying the expression gives the length of MQ in appropriate units (e.g., cm, inches).

What is the definition of a line segment?
A line segment is a straight path connecting two distinct points, known as its endpoints. It represents a portion of a line with a finite length.
How do I calculate the length of a line segment using the distance formula?
The distance formula, also known as the Pythagorean theorem, states that the square of the length of a line segment is equal to the sum of the squares of the differences between the coordinates of its endpoints. In other words, if the endpoints of the line segment are (x1, y1) and (x2, y2), then the length of the line segment is given by: Length = √((x2 – x1)^2 + (y2 – y1)^2)
What are some practical applications of line segment length?
Calculating line segment lengths finds applications in diverse fields such as architecture, engineering, physics, and computer graphics. It is essential for designing structures, determining distances, and analyzing geometric shapes.
