This resource is meant for the exploratory learning approach
The learner is asked to determine what is the angle between a tangent to the circle and radius at the point of contact.
There is feedback to scaffolded questions.
Version 4 allow student to move Point A & B more freely, and line AB may also be not in contact with circle.
This a collaborative effort to design interactive dynamic geometry activities that scaffold student learning of proofs in plane geometry
Members of the team are : Thong Chee Hing, Woo Huey Ming and Vincent Lew Suggestions are most welcome.
