) and an additional 12 workbooks with extra practice problems, to help you test your understanding along the way. Become a Geometry Master is organized into the following sections:

  • Lines and angles, including interior angles of polygons

  • Quadrilaterals, like rectangles, squares, and parallelograms

  • Circles, including arcs, inscribed angles, and chords

  • Area and perimeter for two-dimensional figures

  • Volume and surface area for three-dimensional figures

  • Triangles, including interior angles, bisectors, and circumscribed and inscribed circles

  • Pythagorean theorem and pythagorean inequalities

  • Triangle congruence, including We start from the beginning... I explain the problem setup and why I set it up that way, the steps I take and why I take them, how to work through the yucky, fuzzy middle parts, and how to simplify the answer when you get it.

    Notes: The notes section of each lesson is where you find the most important things to remember. It’s like Cliff Notes for books, but for math. Everything you need to know to pass your class and nothing you don’t.

    Quizzes: When you think you’ve got a good grasp on a topic within a course, you can test your knowledge by taking one of the quizzes. If you pass, great. If not, you can review the videos and notes again or ask for help in the Q&A section.

    Workbooks: Want even more practice? When you've finished the section, you can review everything you've learned by working through the bonus workbook. The workbooks include tons of extra practice problems, so they're a great way to solidify what you just learned in that section.

She not only understands the course material, but also selects/uses excellent application examples for her students and presents them clearly and skillfully using visual teaching aids/tools.” - John

  • “Really good, thorough, well explained lessons.” - Scott F.

  • “This is my second course (algebra previously) from Ms. King's offerings. I enjoyed this course and learned a lot. Each video explains a concept, followed by the working of several examples. I learned the most by listening to Ms King's teaching of the concept, stopping the video, and then attempting to work the example problems. After working the problems, then watching her complete the examples, I found that I really retained the concepts. A great instructor. ” - Charles M.
