(b) Identify the conditions under which given pair of angles are supplementary.

Activity 4: To verify that if two lines intersect at a point, then each pair of vertically opposite angles are equal by paper cutting and pasting.

Activity 5: To verify that if two parallel lines are cut by a transversal, then

- Each pair of corresponding angles are equal
- Each pair of alternate interior angles are equal
- Each pair of interior angles on the same side of transversal are supplementary by paper cutting and pasting.

Activity 6:
