To find the measure or size of a segment, you simply measure its length. What else could you measure? After all, length is the only feature a segment has. You’ve got your short, your medium, and your long segments. (No, these are not technical math terms.) Get ready for another shock: If you’re told that one segment has a length of 10 and another has a length of 20, then the 20-unit segment is twice as long as the 10-unit segment. Fascinating stuff, right?
We explain Line Segments and Distance with video tutorials and quizzes, using our Many Ways(TM) approach from multiple teachers. In this lesson, you'll learn how to apply the idea of measuring a line segment to measuring the distance between two points. Rowinski's Honors Geometry students. Adapted from Geometry (2018 edition) by Glencoe-McGraw Hill. See full list on calcworkshop.com. In the above figure P and Q are two points and the shortest distance between them is called a line segment. Line segments in the above figure – AB, AC, AD, BC, BD & CD. So total line segments – 6 nos. Properties of line segment. Line segment is a path between two points. Cookie 5 5 8 6. It is named using its two end points.

CB = 2 x, BD = 4 x, and BD = 12 $16:(5 x = 3; BC = 6 CB = 4 x ± 9, BD = 3 x + 5, and CD = 17 $16:(5 x = 3; BC = 3 Use the number line to find each measure.
Whenever you look at a diagram in a geometry book, paying attention to the sizes of the segments and angles that make up a shape can help you understand some of the shape’s important properties.
Congruent segments are segments with the same length.
You know that two segments are congruent when you know that they both have the same numerical length or when you don’t know their lengths but you figure out (or are simply told) that they’re congruent. In a figure, giving different segment the same number of tick marks indicates that they’re congruent.
Congruent segments are essential ingredients in proofs. For instance, when you figure out that a side (a segment) of one triangle is congruent to a side of another triangle, you can use that fact to help you prove that the triangles are congruent to each other.
Note that in the two preceding equations, an equal sign is used, not a congruence symbol.

Find the distance between the points $(–5, -1)$ and $(3, 4)$.
Find the distance between the points $left( frac{3}{4} , -3 right)$ and $left( -frac{13}{4}, 5right)$.
Find the midpoint M between $(–3, 5)$ and $(4, –2)$.
Find the midpoint M between $left( frac{1}{2}, frac{5}{3} right)$ and $left( -frac{4}{3}, –2right)$.
How to find distance between two points ?
To find distance between points $A(x_A, y_A)$ and $B(x_B, y_B)$, we use formula:
$$ {color{blue}{ d(A,B) = sqrt{(x_B - x_A)^2 + (y_B-y_A)^2} }} $$Example:
Find distance between points $A(3, -4)$ and $B(-1, 3)$
Solution:
In this example we have: $x_A = 3,~~ y_A = -4,~~ x_B = -1,~~ y_B = 3$. So we have:
$$ begin{aligned} d(A,B) & = sqrt{(x_B - x_A)^2 + (y_B-y_A)^2} d(A,B) & = sqrt{(-1 - 3)^2 + (3 - (-4) )^2} d(A,B) & = sqrt{(-4)^2 + (3 + 4 )^2} d(A,B) & = sqrt{16 + 49} d(A,B) & = sqrt{65} d(A,B) & approx 8.062 end{aligned} $$ Note: use this calculator to find distance and draw graph.

How to find midpoint of line segment ?
The formula for finding the midpoint $M$ of a segment, with endpoints $A(x_A, y_A)$ and $B(x_B, y_B)$, is:
$$ {color{blue}{ M~left(frac{x_A + x_B}{2}, frac{y_A + y_B}{2}right) }} $$Example:
Find midpoint of a segment with endpoints $A(3, -4)$ and $B(-1, 3)$.
Solution:
As in previous example we have: $x_A = 3,~~ y_A = -4,~~ x_B = -1,~~ y_B = 3$~. So we have:
$$ begin{aligned} M~left(frac{x_A + x_B}{2}, frac{y_A + y_B}{2}right) M~left(frac{-1 + 3}{2}, frac{3 - 4}{2}right) M~left(frac{2}{2}, frac{-1}{2}right) M~left(1, frac{-1}{2}right) end{aligned} $$ Quick Calculator Search
