To find the length of a line segment with endpoints: Use the distance formula: d = √ [ (x₂ - x₁)² + (y₂ - y₁)²] Replace the values for the coordinates of the endpoints, (x₁, y₁) and (x₂, y₂). Perform the calculations to get the value of the length of the line segment.

May 30, 2020 · Find the length of the line segment. Answer: Length of DE = 3.61 units (corrected to 3 s.f) or √13 units. 2) Given that we have a line segment FG, where F (-3, 15) and G (9, -4). Find the length of the line segment. Answer: Length of FG = 22.5 units (corrected to 3 s.f) or √505 units. And that’s all we have for today, math students!
Line segments are seen in many common 2D shapes and make up all sides of polygons. For example, Each side of a square is made up of line segments – parts of straight lines. There are also many examples of line segments in real life. For example, A side of a ruler is straight and has clear endpoints. It can be represented with a line segment.
In general (unless the line is purely horizontal or vertical), a line segment and the two corresponding segments according to the two basic directions form a right triangle as the one shown in the figure below, where the x-and y-components of the segment AB, namely AB x and AB y, form the right angle, while the original segment AB forms the third side of the triangle, known in geometry as the ...
Jan 21, 2020 · A line is a perfectly straight path whose length extends indefinitely and has no width. Every line contains infinitely many points and is represented by a straight line with two arrow heads. On the other hand, a line segment has a finite length denoted by its endpoints. The line segment contains infinitely many points between the endpoints and ...
Examples of Line Segments. The most common examples we can see in 2d geometry where all the polygons are made up of line segments. A triangle is made up of three line segments joined end to end. A square is made up of four-line segments. A pentagon is made up of five-line segments.

Example 1: Identify if the given figure is a line segment, a line, or a ray. Solution: The figure has one starting point but an arrow on the other end. This shows that it is not a line segment or a line, it is a ray. Therefore, LM is a ray. Example 2: Name the line segments in the given triangle.
