What is the difference between segment and ray

Place ruler where the arcs cross, and draw the line segment. What is called line? Line actually a straight line , together with point, is a basic concept of elementary geometry. The idea of line is an abstraction that distills our intuition that a straight line is the shortest way between two points.

The point of intersection lies on or belongs to both lines. Parallel lines have no common points. Can a line segment be extended? A line segment is a part of a line. When a line segment from A to B i. AB is extended beyond A in one direction and beyond B in the other direction without any end you get a model for a line. A line has arrows at both ends as it can extend indefinitely in both directions.

What is line and its types? There are four types of lines: horizontal line, vertical line, perpendicular, and parallel lines. They are defined based on their orientation, and the angles if any, formed between them. A ray starts at one point and it continues out to infinity. Student: So, what is the difference between a line and a ray?

Mentor: A line goes on to infinity in both directions, but a ray stops on one end. If you cut a line in half, you make two rays. Now, can anyone guess what a line segment is? Mentor: Exactly right. A line segment is part of a line that has two endpoints. Let's draw one on paper. Student: No. Line-segment 1.

The length of a line-segment is definite. So, it can be measured. There are no end points in a line. There are no end points. So, length of a line cannot be measured. You might like these. Estimation of Line Segments Approximate Value for Measurements We can estimate some lengths and distances using approximate value for measurements. Measurement of Length Handspan Cubit Footspan Stride We can measure objects by comparing them with other objects like clips, ribbons, pencils or using our body parts for example handspan, foot, cubit and stride.

Lines passing through a point O. Ray 1. Two lines can be parallel or perpendicular.

The lines may be thick or thin. Curved lines also change directions. A line segment is a collection of finite points which has a definite length. It has a start point and an endpoint. It is the shortest distance between two points that can be measured.

We can measure its length using a ruler or an inch scale. A line segment is a part of a line. Below is a line segment AB. Any 2-d shape is made up of line segments. Here are a few polygons. We can observe that a triangle is made up of 3 line segments, a pentagon is made up of 5 line segments and the quadrilaterals are made up of 4 line segments.
