Learning Objectives
- • Understand the perpendicular relationship between tangents and radii
- • Apply the shortest distance principle in geometric proofs
- • Visualize abstract geometric concepts through interaction
Quick Tips
- 💡 Try dragging P to different positions on the circle
- 💡 Move Q far from P to see the distance difference clearly
- 💡 Notice how the angle marker always shows 90°
