The length of a line is not necessarily a practical value as a line goes on for ever. The length of a line is infinite. However, the length of a line segment is of more value and is a finite value. Any time we measure how long a package is or how long our table is, we are taking the length of a line segment. Learn the formula for finding the length of a line segment when given two points in either 2 dimensions or in 3 dimensions.
Given two points it may be necessary to find the midpoint of the line between the two points. Learn about the midpoint formula for finding the midpoint of a line segment.
Learn what collinear points are. Practice finding and determining if sets of points are indeed collinear.
Two lines on the Cartesian plane are either parallel or intersecting. If lines are intersecting, we want to find where they cross or their point of intersection.
Learn about parallel lines and their properties. How are the slopes of parallel lines related? Practice finding the equations of parallel lines.
Learn how to find the slope of a line perpendicular to a given line. Practice finding the equation of a line perpendicular to a given line.
