Expert Answer:

Model-1: Angle of incidence = Angle of reflection
 
Using the scale and mirror with laser light you can easily show the angle of incidence equals to angle of reflection. 
 
 
Model-2: Area of circle by cutting it into sectors.
 
You can explain this by taking real life example of a 'pizza'.  Cut the pizza into several part. Each part is a sector.
Area of circle = sum of the areas of all the sectors.
