Book description:

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.
