{ "item_title" : "Help Me Understand Right Triangles and Plane Trigonometry", "item_author" : [" Anthony J. Pultrone "], "item_description" : "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 PropertiesThe Pythagorean TheoremSpecial Right Triangles: Right Isosceles or 45-45-90Special Right Triangles: 30-60-90Plane Trigonometry or Trigonometry of Right Triangles (SOH-CAH-TOA)Perimeter of Right TrianglesArea of Right TrianglesCoordinate Geometry with Right Triangles and the Distance FormulaInscribed Right TrianglesCoordinate Geometry with Inscribed Right TrianglesCircumscribed Right TrianglesCoordinate Geometry with Circumscribed Right TrianglesCentroid of TrianglesOrthocenter of Triangles", "item_img_path" : "https://covers1.booksamillion.com/covers/bam/9/79/834/492/9798344925912_b.jpg", "price_data" : { "retail_price" : "14.99", "online_price" : "14.99", "our_price" : "14.99", "club_price" : "14.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
