Inscribed Circles and Their Central Angles
- Lee Lancaster
Investigate the relationship between inscribed angles and arc lengths.
Q1. If the diameter of circle d is twice that of circle a, then what is the relationship between the length of BE and the length of CF? (Hint: Drag point B until alpha = 180 degrees.) Q2. How can you use the answer to Q1 to show that the measure of angle beta is always twice that of angle alpha?
