Circle Theorem 1
1. Move the Points & Observe
- Click and drag the movable points to see how the angles and lengths change (or stay the same).
- Pay close attention to the measurements and write down any patterns you notice.
- What do you observe about the lengths AB and AC?
- What do you observe about the angles OAC and OAB?
- What do you observe about the angles AOC and AOB?
- What do you notice about the angles between the tangent and the radius?
