Construct the following angles at the initial point of a given ray and justify the construction: (i) `45^0` (ii) `90^0`

Explanation

To construct the angles of \(45^\circ\) and \(90^\circ\) at the initial point of a given ray, follow these steps:

### Construction of \(90^\circ\) Angle

1. **Draw a Ray**: Start by drawing a straight ray \(OA\) with point \(O\) as the initial point.

**Hint**: Use a ruler to ensure the line is straight.
