How do we measure length? We use established units that define a specific amount of length. Length is a measure of distance so, finding the length of the line segment that joins two points in space would give us the distance between the two points. Linear measure is the measurement of the length of a line segment. As it joins the points A and B, it can be referred to as AB. This figure provides an example of a line segment as it has two endpoints and doesn't extend infinitely. This means that the 'lines' we typically see are geometrically defined as line segments.Ī line segment AB, Jones - StudySmarter Originals Line segments are parts of lines that join two points together. Lines join two points and extend to infinity. Racing tracks need to be measured with maximum precision to make sure they are the same length as other tracks and ensure fairness when recording times for races. Contractors need to take accurate measurements of dimensions of materials based on the architects' designs in order to build structurally-sound buildings. For example, scientists need to take accurate and precise measurements in order to draw valid conclusions from experiments. In real life, there are countless applications of linear measure as length often needs to be measured.
