This course is an introduction to the elements of geometry, including points, lines, planes, and angles. These elements are used in conjunction with triangles, polygonal and circular figures in both two and three dimensional configurations. This course is intended for students who have not had or completed two semesters of high school geometry or who need a refresher prior to taking trigonometry.

This video continues introducing the basic building blocks for the successful study of geometry. This video reviews the basic concepts associated with sets. In addition, this video goes over 6 examples involving the union and intersection of geometric figures.

This video introduces the basic concepts associated with measurement of segments. Topics covered: Measuring Segments and Congruent Segments.

In this video we will review how to name angles, we will then go over how to measure angles.

In this video we will go over the concepts of collinearity, betweenness of points, triangle inequality, and assumptions from diagrams.

In this video we will learn how to write simple two-column proofs. We will first cover algebraic proofs, then we will go over the elements of an axiomatic system, the video ends with an introduction to geometric proofs.

In this video we will go over how to identify midpoints, bisectors of segments, trisection points, trisectors of segments, adjacent angles, angle bisectors and angle trisectors.
