Question 6 Delete AC and focus on the intersection of AB and BC. Keeping points B and C fixed, move point A to different locations and observe how
ZABC changes. What must you do to increase or decrease m ABC ? What happens if you move point A to a location directly on CB? What is
mZABC at this location? Explain.
