Geometry deals with shapes and the properties of those shapes. This documents discusses basic concepts of geometry. This e-book will be useful to students taking Geometry in high school and will become handy to those taking the SAT , GRE, GMAT Math section. The topics that are discussed in this e-book are as follows: 1. Polygons 2. Angles 3. Angles Properties in Circles 4. Circles, Chords, Tangents and Quadrilaterals

In this e-document, I will examine basic area concepts that relate to the process of finding the area of a square and rectangle. Manipulation facts are also discussed. Using this document, instructors can have students work in groups and have them find areas of irregular figures that can be portioned into squares and rectangles. The formulas for for finding the finding the areas of squares and rectangles are also given.

The surface area of a solid object is a measure of the total area that the surface of an object occupies. This e-book details how to find the surface area of rectangular, triangular and cylindrical prisms. In geometry, a rectangular prism has 2 ends and 4 sides. Opposite sides have the same area. The surface area is the sum of the areas of all six sides. On the other hand, a triangular prism is a three-sided prism; it is a polyhedron made of a triangular base, a translated copy, and 3 faces joi

How to circumscribe a circle on a triangle by using a pair of compass and a ruler.

How to construct a rhombus with a pair of compass and a ruler or straight edge

In this document, the students will learn how to find measures of angles formed by chords, secant and tangent lines. In this e-document, you will encounter examples that are easy to follow along. At the end of the document, an exercise is given and solutions to the questions asked are provided.

The Law of Cosines is a law that features in geometry and is often used to find the length of an unknown side of a triangle when the length of two sides of the triangle and the measure of the angle they form are known. This angle is called the included angle. Knowing two sides and the included angle is referred to as SAS. The triangles given are not right triangles. This document gives sufficient examples about this concept. It also discusses the rules used to solve the triangle.

The students will solve real-world and mathematical problems involving volume of cylinders, cones, and spheres. At the end of this lesson, the students should know the formulas for the volumes of cones, cylinders, and spheres and how to use them to solve volume related problems.
