Fold the paper, so that it forms a straight line. Fold once again, in such a way that
the impression created is equidistant from the previous impression at all the points.
The impressions created form two parallel lines.
If a third line is formed in such a way that it cuts the earlier two lines at two different
points then this line becomes a transversal.
Note : A line which cuts two other lines at two different points is called a transversal.
- Perpendicular bisector
Fold the paper vertically to form exactly two halves. Similarly, fold again horizontally.
The two impressions created are perpendicular bisectors to each other.
- Right Angle
Any neatly cut paper will form a right angle at its vertices.
