Parallel Lines in Cross Pattern: Identifying 6 Line Pairs with Right Angles

Let's remember that parallel lines are two straight lines that lie in the same plane and never intersect (do not cross).

Let's draw all the right angles in the drawing, and extend the lines to create parallel lines, as follows:

We saw that we marked 8 right angles in the drawing, now let's mark each pair of parallel lines:

Note that in the drawing we marked 6 pairs of parallel lines.
