The simple experiment demonstrates that all the angles inscribed in a chord are equal. Fold a chord in a 20-cm diameter circle. Fold an arbitrary chord PQ and mark it with a pen. Mark an angle on the chord PQ touching the circumference. Name this angle A. Then make another angle B on base PQ and inscribed in the circle. Similarly, make angle C. All angles A, B and C will measure the same. You can prove this by placing a piece of paper and folding angle A. Then place this template on angle B and C to prove that they were equal to A.
