Construction #1: Rescue Grandma using Geometrical Construction!

Read the scenario below carefully. We had a brief discussion in class. 

Try this on the handout. 

We shall discuss this when we meet on MONDAY

Construction #2: Where are You, Celine? Where Shall We Meet?

Read the scenario below. Try figure out how you could locate the meeting point the three friends..

We shall discuss this when we meet on MONDAY.

Angles involving Parallel lines and Transverals

In the class, we discussed how to approach the questions and learnt that there are usually multiple ways to solve the same problem. This also implies the clarity of presentation is important so that one can follow your train of thought. 

Here are examples the problems can be solved. 

IMPORTANT: Look out for how the angle properties are presented
