===Process (How to do the activity)===
# Prior hands on activity (optional – children can use 2 strips newspaper or sticks to form vertically opposite angles and note the changes in the angles with change in the position of the strips or sticks).
# Students to identify number of angles formed when the two lines cross each other
What kinds of questions you can ask for that activity
# Name the all the angles formed around the point
# Do the angles formed have a relation
# Identify angles on AB: what do the form together
# Identify angles on CD: what do they form together
# What is observed about these angle pairs on the two lines
# Can you find other pair of angles on line AB and CD
# What is common about these angles
# Record the values of the angles formed and their sum in the worksheet

* '''Evaluation at the end of the activity'''
# What is the angle measure of the sum of any two adjacent angles when two lines intersect?
# What is the total measure of all the angles formed when two lines intersect?
