3/1/2021 Unit Activity: Circle Theorems ; 1/4 Task 3 Circle Theorems In this unit, you learned about some of the important properties of circles. Let’s take a look at a property of circles that might be new to you. You will use GeoGebra to demonstrate a theorem about chords and radii. Open GeoGebra , and complete each step below. Part A Construct a circle of any radius, and draw a chord on it. Then construct the radius of the circle that bisects the chord. Measure the angle between the chord and the radius. What can you conclude about the intersection of a chord and the radius that bisects it? Take a screenshot of your construction, save it, and insert the image below your answer. Answer: OB is perpendicular to AC. Characters used: 26 / 15000
