Lines and Angles : Introduction, Properties and Theorems

Objectives

 * Introducing lines, rays and line segments
 * Understanding formation of angles and their types
 * Differentiating parallel lines and non-parallel lines
 * Recognizing angles, pairs of angles formed in parallel lines
 * To visualize geometrical ideas with real life situations

Introduction
You will explore the angles formed when two lines intersect each other, as well as the angles formed when a line intersects two or more parallel lines at distinct points. You will then use these properties to usedeductive reasoning to prove some statements.

Basic terms and Definitions
