Linear measurement is key in fields like physics, engineering, and construction, where distance between two points is crucial. This overview covers the basics of lines and segments, the importance of precision, tools for measuring length, and understanding of both imperial and metric systems. It also touches on geometric principles such as collinearity and the segment addition postulate, essential for solving geometric problems.
