To create a diagram of two intersecting lines that both contain point M and are parallel to a third line $xy$, follow these steps:

1. Line $xy$: First, draw a line $xy$ as a reference line.
2. Point M: Mark a point $M$ somewhere not on line $xy$.
3. Parallel Lines to $xy$: Draw two lines through point $M$, ensuring that both lines are parallel to line $xy$. These lines should intersect each other at point $M$.
