segment – a part of a line that consists of 2 points, called endpoints, and all the points between them A C AC AC refers to the segment AC refers to the length of AC
Measuring Line Segments Unlike a line, a line segment , or segment, can be measured because it has two endpoints. The length of a segment is only as precise as the smallest unit on the measuring device. The precision of any measurement depends on the smallest unit available on the measuring tool. The measurement should be precise to within 0.5 unit of measurement.

Unformatted text preview: is a real number n between a and b such that a < n < c. Point n is between points a and c iff a, n, and c are collinear and an + nc = ac a n c Constructions Constructions are methods of creating geometric figures without the benefit of measuring tools. Generally, only a pencil, straightedge, and compass are used in constructions.
