Granddaddy Parallelogram and his grandchildren, Rect the Rectangle and Rhombella the Rhombus, live in the land of quadrilaterals. It is an exciting place to be, but Rect and Rhombella have difficulty accepting each others differences. As a result, Rect and Rhombella dispute continuously. Their disagreements cease with self-discovery and a secret from their astute grandfather, Granddaddy Parallelogram. With vibrant color illustrations and accompanying stories children can relate to, the Granddaddy Parallelogram series is a useful tool to teach children advance geometric concepts initially. Children will enjoy entering the land of quadrilaterals and the engaging activities offered to parents and teachers to enhance their childrens knowledge. Experience gratification in math and adventures with the entire Granddaddy Parallelogram series.

Get all 4 books in the PARALLELOGRAM series—all in one specially-priced boxed set! Audie Masters is a 17-year old girl who doesn’t have it all: not a lot of money, not much confidence around guys, she can’t seem to pass algebra, and she’s desperate to get into the college she’s been dreaming of for years. But what Audie does have is a knack for physics that’s about to catapult her into the adventure of a lifetime. Now all she has to do is survive it.

Make gerometry paractice easy and dun! Geometry is one of the oldest mathematical subjects in history. Unfortunately, few geometry study guides offer clear explanations, causing many people to get tripped up or lost when trying to solve a proof—even when they know the terms and concepts like the back of their hand. However, this problem can be fixed with practice and some strategies for slicing through all the mumbo-jumbo and getting right to the heart of the proof. Geometry Workbook For Dummies ensures that practice makes perfect, especially when problems are presented without the stiff, formal style that you’d find in your math textbook. Written with a commonsense, street-smart approach, this guide gives you the step-by-step process to solve each proof, along with tips, shortcuts, and mnemonic devices to make sure the solutions stick. It also gives you plenty of room to work out your solutions, providing you with space to breathe and a clear head. This book provides you with the tools you need to solve all types of geometry problems, including: Congruent triangles Finding the area, angle, and size of quadrilaterals Angle-arc theorems and formulas Touching radii and tangents Connecting radii and chords Parallel, perpendicular, and intersecting lines and planes Slope, distance, and midpoint formulas Line and circle equations Handling rotations, reflections, and other transformations Packed with tons of strategies for solving proofs and a review of key concepts, Geometry Workbook For Dummies is the ultimate study aid for students, parents, and anyone with an interest in the field.

Including a CD-ROM with Logo software and 300 Logo projects and graphics, this cartoon-illustrated family activity book explores the Logo language on and off the computer. Logo is a computer language where children can control the actions of a cybernetic turtle on the screen. Two- and three-dimensional geometry, trigonometry, multimedia, animation, and simulations are all covered.

The magic square can be a magic stacked parallelogram and the corner numbers of these 16 parallelograms, as do the 4 numbers in each of the four vertical lines. The parallelogram can be mapped from the order-4 pantriagonal magic square. You have some numbers and you have to fill all missing numbers.
