the points a, b, c and d all lie on the same line segment, in that order, such that the ratio of ab:bc:cd ab:bc:cd is equal to 1:4:1.1:4:1. if ad


Let me explain to you what a line segment is. In geometry, a line segment is defined by two distinct points that serve as its boundaries. It can also be referred to as a section of a line connecting two specific locations. Unlike a line, which can extend infinitely in both directions without any endpoints, a line segment has two finite endpoints. These endpoints, along with all the points that lie on the line between them, are part of the segment. Another distinction between a line and a line segment is that a segment's length can be measured, while a line's length cannot be determined. To identify a segment, we need to know its two endpoints. Let's use an example to further illustrate this concept. If we have a line segment AD that measures 18 units, and we know that the ratio of AB to BC to CD is 1:4:1, we can use this information to determine the length of the segment. We can assume that AB is represented by the variable x, which means that BC is 4 times as long (4x) and CD is equal to x. To calculate the length of AD, we add the lengths of AB, BC, and CD. Setting up the equation 18=x+4x+x and solving for x, we get x=3. Therefore, CD, which is equal to x, also measures 3 units. Hence, the length of the line segment is 3 units.
