All of the site's resources are available to anyone.

It doesn't matter if you are a student, teacher, home-schooler, principal, adult returning to the classroom after 20 years, or a friendly extra-terrestrial who is trying to get a leg up on earth biology.

The Khan Academy's materials and resources are available to you completely free of charge.

Videos on geometry. After Basic Geometry list, videos assume you know introductory algebra concepts. After these videos, you'll be ready for Trigonometry.

Geometry - Introduction to Euclidean geometry (High School Geometry)

• Understanding the purpose, notation, and building blocks of geometry.

Angles

• Identifying, measuring, and calculating angles.

Triangles

• Identifying types of triangles, using principles of similarity and congruence, and applying and proving triangle postulates.

Quadrilaterals

• Identifying types of quadrilaterals, finding measurements, and applying and proving postulates.

Circles

• Finding measurements and applying and proving circle theorems.

Worked examples

• 80 problems from the released questions from the California Standards Test for Geometry. Basic understanding of Algebra I necessary.

Trigonometry

• Videos on trigonometry. Watch the "Geometry" playlist first if you have trouble understanding the topics covered here.
