Prove The angle between two tangents to a circle may be `0^(@)`.

Explanation

To prove that the angle between two tangents to a circle may be \(0^\circ\), we can follow these steps:

### Step 1: Understand the Setup
Consider a circle with center \(O\) and a point \(P\) outside the circle. From point \(P\), we can draw two tangents to the circle, touching the circle at points \(A\) and \(B\).

### Step 2: Draw the Tangents
Draw the tangents \(PA\) and \(PB\) such that they touch the circle at points \(A\) and \(B\) respectively.
