Then join the third stick to them at the endpoint where the two sticks meet. Let the students draw the pattern and measure the angles formed. The three sticks form adjacent angles whose sum is 180 degrees . Discuss with the students the fact that angles are a part of their daily lives. Streets and buildings are constructed using angles.
Airplanes take off on angles.
Installation of revolving doors involve the use of angles. The military bombers fire at angles. This experiment gives students a visual appreciation of geometric vocabulary. They can experiment at home with pieces of spaghetti. As homework, let the students classify the different angles in their classroom and environment.
