Summit Math Algebra 2 Book 8: The Pythagorean Theorem & Special Right Triangles (2nd Edition)
In this book, students will review the Pythagorean Theorem and then learn that they can use right triangles to create the Distance Formula. They will discover that they can use squares to learn about 45-45-90 triangles. They will realize that 30-60-90 triangles are hidden inside equilateral triangles. They will use the Pythagorean Theorem in many different ways as they encounter a wide variety of right triangle scenarios. This book comes at the end of the Algebra 2 Series to prepare students for future learning in Geometry and Trigonometry.

If you are searching for an independent algebra program or a supplement to teach specific algebra concepts, Summit Math is worth your consideration. Using the guided discovery method, students make their own connections as they learn to master each scenario before moving on to the next. Each section builds on previous concepts already learned. The first half of the book incorporates the guided discovery approach, while the latter half uses extra practice sheets to improve understanding of the topics. Each section has an answer key. A placement test and pacing guide is provided for each level. The author states this is a complete program teaching typical topics in the Algebra I and II sequence while preparing students for standardized testing. If students feel they need extra instruction, a video subscription is available from the publisher. Free downloadable tests and a more detailed version of the answer key are also available at the publisher’s website.
