Also, if two lines are perpendicular, their slope is -1.Įxample 2: In the following figure, mention all the line segments. Understanding Line Segment Examples with SolutionsĮxample 1: How would you know if the given two line segments are perpendicular to each other?Īnswer: If two line segments intersect each other at 90 degrees, then the two line segments are perpendicular to each other. Therefore, line segments perform a crucial function in geometry. A pentagon is made up of five-line segments.A rectangle is made up of four-line segments.A hexagon is made up of six-line segments joined end to end.The most prevalent examples are seen in 2D geometry, where each polygon is constructed of a series of line segments. So, PQ is the required line segment of length 8 cm. Mark an arc with the same measurement using a pencil. Step 4: Now, place the pointer of the compass at point P on the line. Step 3: Now place the ruler and find the pointer of the compass 8cm apart from the tip of the pencil’s lead. This will be the starting point of the line segment. This can be without any measurement, although we must consider the length of the line segment. Step 1: Firstly, we will draw a line of any length. Steps to constructing a line segment PQ of length 8 cm with the help of a ruler and compass. Step 5: Join A and B to get the required line segment of the length of 10cm. Step 4: Locate the 10 cm on the line drawn with the help of a ruler and mark a point B. Step 3: Now, we will align a scale or ruler such that mark A coincides with 0 on the ruler. Step 2: Mark a point A on the line, which is the starting point of the line segment. Step 1: We will draw a line of any length ( keeping the length of the line segment, i.e., 10 cm, into consideration) The following steps describe how to draw a line segment of 10 cm with the help of a measuring ruler or scale. Now, notice which one is longer compared with the other. To do this precisely, we will place the tracing paper on the other line segment. Next, we will compare it with the other segment. We can compare two line segments using the support of a tracing paper. However, this method has several constraints, and we cannot rely completely on observation to compare two line segments. On observing, you can easily predict which one is long or short compared to the other. The most trivial strategy to find the length of a line segment is to compare two line segments by simple observation. Here we will learn three different methods. There are several methods to find the length of a line segment. How to Find the Length of a Line Segment? Thus, the formula is:ĭ =√(x 2– x 1) 2+(y 2 – y 1) 2 Line Segment Calculation Example Example 1: What is the distance between two coordinates A (5, -13) and B (-3, 4)? Solution: We can calculate the distance between the coordinates using the distance formula. Since a line segment is a distance between two points, we can use the distance formula to calculate the length of the line segment. The starting point of the sun’s rays is the sun but there is no endpoint. This arrow represents that the line goes on forever.Įxample: a line that you see without initial and endpoints.Ī ruler, a pencil, and a stick are examples of a line segment in real life.Īn example of a ray is the sun’s rays. A line is a straight figure that extends in two directions indefinitely.Ī segment is part of a line with a definite starting point and a definite endpoint.Ī ray has a definite starting point, but no endpoint.Ī line is represented by arrows on both ends.Ī line segment is represented by endpoints.Ī ray is represented by a point at one end, which is the starting point, and an arrow at the other end.
