Why does the Thales-circle construction give a tangent?
Choose the correct explanation.
What does the generator do?
The generator shows a circle, an external point P, the Thales circle over MP and the touch point T with the right angle, and offers four statements.
How to solve
Remember that a tangent is perpendicular to the radius at the touch point. The Thales circle over MP creates exactly this right angle at T.
