Indicate which pairs of angles are:(i) Vertically opposite angles.        (ii) Linear pairs.

Explanation

To solve the question of identifying vertically opposite angles and linear pairs, we can follow these steps:

### Step 1: Identify Vertically Opposite Angles
1. **Definition**: Vertically opposite angles are the angles that are opposite each other when two lines intersect. They are equal in measure.
2. **Identification**:
- Look at the angles formed by the intersection of two lines.
- For example, if we have angles labeled as 1, 2, 3, 4, and 5:
- Angle 1 and Angle 4 are vertically opposite.
