Formation of an Angle between the Lines

Definition

The formation of an angle, when lines meet at a point is called the formation of angle between lines.

Introduction

Geometrically, an angle is formed between any two straight lines, when two straight lines meet at a point. So, it is called the formation of an angle between the straight lines.

It is another geometric theory to explain the formation of an angle between two straight lines. Now, let’s learn how an angle is formed between two straight lines from an understandable graphical animation.

Example

Firstly, let’s draw a geometric figure by the following steps.

1. Let’s consider a point and denote it by $O$ on a plane.
2. Draw a straight lines from that point and assume that it passes through a point $P$.
3. Similarly, draw another straight lines from that point and assume that it passes through a point $Q$.

Now, an angle is formed between the two rays $\overrightarrow{OP}$ and $\overrightarrow{OQ}$ at point $O$ because of their meeting.

In this way, an angle can be formed between any two straight lines, when the straight lines meet at a point. So, it is called the formation of an angle between the straight lines.
