Transversal lines
A transversal line is a line that cuts two or more lines. We will learn about the
angles that are formed when two parallel lines are cut by a transversal line.

Let us find out the size of the angles

formed when a transversal line
is //. I
crosses a pair of parallel lines.
Q Use your protractor to measure:
a) Angles 0 and b b) Angles c and d
