About
Hey guys,
Since there was much demand for my original series on high school geometry, I decided to make a new, comprehensive series on Geometry, from the very basics to advanced trigonometry.
IMPORTANT: You can join this series AFTER it has begun in case there are any specific topics you would like to learn or review!
As I said, in this series we will covering all Khan Academy Courses on Basic Geometry, High School Geometry, and Trigonometry.
The units we'll be doing are the following:
Geometry Foundations, Triangles, Area and Perimeter, Surface Area and Volume, Polygons, Performing Transformations, Transformation properties and proofs, Congruence, Similarity, Right angles and trigonometry, Advanced Trigonometry, Analytical Geometry, Conic Sections, Circles, and Solid Geometry.
This series is for students who have already completed Prealgebra and Arithmetic and are eager to learn! This series is also intended for learners who learn better through conversation and discussion rather than idle videos.
Tutored by
A little about me: I'm about the biggest Indie fan there is, I almost exclusively watch (John Hughes>>) 80s movies or the upcoming Star Wars series, and I read sci-fi in my spare time. I tutor for the sake of those aha moments, and have taken Multivariable Calc, Linear Algebra, Real Analysis, and Complex Analysis. Who knows what I'll tutor next, hope to see you soon.

Geometry foundations
Geometry foundations
Sun 12:30 AM - 2:00 AM UTCOct 17, 12:30 AM - 2:00 AM UTC
Hey guys,
Today we will be covering the Lines and Angle units on Khan Academy. We will cover the following:
1. Definitions of points, rays, lines, line segments, and angles
2. Basic definitions of parallel and perpendicular lines
3. Vertical, complementary, and supplementary angles
4. Angle theorems having to do with parallel lines
This will be very important as we begin our journey to learn geometry. If you cannot make it to this session (or have to join late/leave early please send me a private chat--I will do my best to set up a catch-up session. Like any other branch of math, geometry is foundational and we cannot move on to more advanced topics until we have mastered the basics. Anyways, thanks for joining the series and I hope to see you soon!

Hey everyone,
Today we will review non-rigid transformation (dilation) properties and will derive similarity theorems such as AA, AAA, and the angle bisector theorem. We'll also learn about ratios proportions, and how to solve basic rational equations. We'll use all of this to find the missing side lengths of figures. All of this will be particularly important as we enter our next unit which is on Trigonometry.
