Basics of Geometry
Tutorial Name
Tutorial Description
Describes the ruler postulate and how to use it to find the length of either a horizontal or vertical segment.
Describes what the segment addition postulate is and some of the ways it is used.
Introduces the distance formula and contrasts it with the Pythagorean theorem and the SAS method for finding distance between two points on a coordinate plane.
The Midpoint Formula Partitioning a segment Describes how to partition a segment on a number line. To partition a segment on a coordinate plane go to Parallel and Perpendicular Lines tutorials.
