Choose the correct construction of a right triangle over the hypotenuse AB.
Given: c = AB = 6 cm
What does the generator do?
The generator offers four constructions. Only one has a circle centred at the midpoint of AB with radius |AB|/2 and point C on it — that is the correct Thales construction.
How to solve
Look for the circle whose diameter is exactly the hypotenuse AB (centre at the midpoint of AB). Point C must lie on this circle for a right angle to appear.
