Question
Find the equations of the lines joining the following pairs of vertices and then find the shortest distance between the lines
(i) (0, 0, 0) and (1, 0, 2)
Solution
The equation of the line passing through the points (0, 0, 0) and (1, 0, 2) is
\[\frac{x - 0}{1 - 0} = \frac{y - 0}{0 - 0} = \frac{z - 0}{2 - 0}\]
\[ = \frac{x}{1} = \frac{y}{0} = \frac{z}{2}\]
