Line Segment
A line segment is a part of a line that is bounded by two distinct endpoints. It consists of all the points on a line that are between two given points.
Properties of a Line Segment:
- It has a definite length.
- It is a straight path that connects two points.
- It has two endpoints.
- It can be measured using a ruler or a measuring tape.
Notation of Line Segment:
A line segment is often named by its two endpoints. For example, if the endpoints are A and B, the line segment would be denoted as AB or BA.
Examples of Line Segments:
Examples of line segments include the sides of a triangle, the edges of a rectangle, and the spokes of a bicycle wheel.
Study Guide for Line Segments:
- Understand the concept of a line segment as a part of a line with two distinct endpoints.
- Learn the properties of a line segment, such as its length and straight path.
- Practice measuring line segments using a ruler or a measuring tape to understand the concept of length.
- Identify and analyze examples of line segments in everyday objects and shapes.

Grade 7 Curriculum Focal Points (NCTM)
Number and Operations and Algebra: Developing an understanding of operations on all rational numbers and solving linear equations
Students extend understandings of addition, subtraction, multiplication, and division, together with their properties, to all rational numbers, including negative integers. By applying properties of arithmetic and considering negative numbers in everyday contexts (e.g., situations of owing money or measuring elevations above and below sea level), students explain why the rules for adding, subtracting, multiplying, and dividing with negative numbers make sense. They use the arithmetic of rational numbers as they formulate and solve linear equations in one variable and use these equations to solve problems. Students make strategic choices of procedures to solve linear equations in one variable and implement them efficiently, understanding that when they use the properties of equality to express an equation in a new way, solutions that they obtain for the new equation also solve the original equation.
