  15. Ask students to brainstorm how angles are used in the world around us. Some examples: • When parking a car a driver uses the concept of angles to park in a particular space, especially when parallel parking. • A contractor uses angles to build a house, a school, or any structure. • A student places books on a shelf at a slight angle to prevent them from tipping over.

  16. ANGLES: OUR EVERYDAY LIVES  • Architecture • Carpentry /people that make things • Engineers • Art • Clocks/ watches • All forms of aircraft: specific angles to land • Ship navigation • The Alphabet: Letters such as: L, Y, Z, V, have different angles • Relationship between sun, objects and shadow • Some sports: throwing javelin ( Keshorn Walcott) • Rotation of Planets at different positions • Math: Geometry- Lines and shapes etc.  One can almost not live without encountering angles in real life. They are everywhere.
