Introduction

 

In geometry, the lines and angles are important tools. A line is a collection of points along a straight path, it extends in both the directions and has no endpoints. It has no definite length. An angle is a figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.

1. An angle is a union of two non-collinear rays with a common initial point.
2. Two adjacent angles are said to form a linear pair if their sum is 180°. Non-common arms of the linear pair of angles form a straight line.
3. Sum of the angles around a point is equal to 360°.
4. Two rays originating from the same endpoint form an angle.
