Angles Inscribed to a Semicircle
- Jose Mari M. Calamlam
Given segment AB is a diameter, what kind of arc is arc AB? (Please review basics of circles)
What do you observe with the measures of angles ACB and ADB?
Move vertices C and D along the circle, is there any changes on the measures angles ACB and ADB?
Based on your observations on angles ACB and ADB, what can you conclude to angles inscribed to a semicircle?
