Help Me Understand Right Triangles and Plane Trigonometry (Paperback) (ISBN-13: 9798344925912)

"Help Me Understand Right Triangles and Plane Trigonometry" is a tutorial and workbook that will help students in a Geometry class better understand the properties of right triangles, both visually and mathematically. This book is not a proof-based approach, but rather a more visual approach to understanding right triangles. (The book assumes that students have a solid understanding of basic Algebra, including exponents, fractions, and radicals) and that the students are enrolled in a middle (junior high) or high school Geometry class.

This workbook include explanations of the following topics. Most sections also include numerous practice problems with fully worked answers.

• General Right Triangles & Their Properties
• The Pythagorean Theorem
• Special Right Triangles: Right Isosceles or 45-45-90
• Special Right Triangles: 30-60-90
• Plane Trigonometry or Trigonometry of Right Triangles (SOH-CAH-TOA)
• Perimeter of Right Triangles
• Area of Right Triangles
• Coordinate Geometry with Right Triangles and the Distance Formula
• Inscribed Right Triangles
• Coordinate Geometry with Inscribed Right Triangles
• Circumscribed Right Triangles
• Coordinate Geometry with Circumscribed Right Triangles
• Centroid of Triangles
• Orthocenter of Triangles
