Question

Place a ruler on a sheet of paper. Draw two lines along the two edges of the ruler. You now have a
pair of parallel lines. Draw a transversal cutting the parallel lines at any angle. Name the eight angles
Maths Lab Activity
formed as given in the figure.
Cut out 21, 22, 23 and 24. Place them on 25, 26, 27 and 28 respectively.
You will find that the angles fit exactly. This proves that corresponding angles
are equal.
Similarly, prove that alternate interior angles are equal by placing Z3 on Z5 and
24 on 26. How will you place the angles to prove that alternate exterior angles
are equal?
