# Formation of an angle between lines

An angle formed between two lines which have common intersecting point is called an angle formed between the lines.

## Example

An angle can be formed between two lines when they both have common intersecting point.

For example, $\overrightarrow{RS}$ and $\overrightarrow{RT}$ are two rays and they both are started from point $R$. Thus, an angle is formed between them.

The angle formed between them is represented by $\angle SRT$ or $\angle TRS$ mathematically.
