Show that the line through the points `(1, 1, 2), (3, 4, 2)` is perpendicular to the line through the points (0, 3, 2) and (3, 5, 6).

Explanation

To show that the line through the points \( (1, 1, 2) \) and \( (3, 4, 2) \) is perpendicular to the line through the points \( (0, 3, 2) \) and \( (3, 5, 6) \), we will follow these steps:

### Step 1: Find the direction ratios of the first line
The direction ratios of a line passing through two points \( (x_1, y_1, z_1) \) and \( (x_2, y_2, z_2) \) can be found by subtracting the coordinates of the first point from the second point.

For the first line through points \( (1, 1, 2) \) and \( (3, 4, 2) \):
- Direction ratios \( L_1 = (3 - 1, 4 - 1, 2 - 2) = (2, 3, 0) \).
