Geometry Essentials For Dummies

by Mark Ryan

Just the critical concepts you need to score high in geometry This practical, friendly guide focuses on critical concepts taught in a typical geometry course, from the properties of triangles, parallelograms, circles, and cylinders, to the skills and strategies you need to write geometry proofs. Geometry Essentials For Dummies is perfect for cramming or doing homework, or as a reference for parents helping kids study for exams.

Get down to the basics — get a handle on the basics of geometry, from lines, segments, and angles, to vertices, altitudes, and diagonals

Conquer proofs with confidence — follow easy-to-grasp instructions for understanding the components of a formal geometry proof

Take triangles in strides — learn how to take in a triangle's sides, analyze its angles, work through an SAS proof, and apply the Pythagorean Theorem

Polish up on polygons — get the lowdown on quadrilaterals and other their angles, areas, properties, perimeters, and much more

nice refresher on geometry . more study on the way, geometry is a must subject.

[Dandy Lyons · Rating 3 out of 5]

For the coming spring I decided to register for a calculus class and I thought it would be a good idea to refresh my understanding of trigonometry since it has been a long time since I have done any math classes. While reviewing some trig books I realized I needed to take another step back and review some geometry. This was an excellent for refreshing that dormant geometry knowledge in my head. Took about 3-4 hours to work through all the examples in the book.

A great review for people who understand algebra and pick up math concepts okay. Not for those who struggle.
