Anita wants to construct a parallel line using a set square and a ruler. She noted down the steps in a jumbled order help her arrange in correct sequential order.
1. Draw a line XY using ruler and mark a point A on it and perpendicular line AM.
2. Through M, draw a line MN along the edge.
3. Pressing tightly the ruler, slide the set square along the ruler till the edge of the set square touches the point M.
4. MN is the required line parallel to XY through M.
