- Fedrick ThomasProve that the parallelogram circumscribing a circle is a rhombus.

- Harsh SolankiProve that the angle between the two tangents drawn from an external point to a circle is supplementary to the angle subtended by the line-segment joining the points of the contact at the center.

- Emily ThomasIn the given figure, XY and X'Y' are two parallel tangents to a circle with center O and another tangent AB with the point of contact C intersecting XY and X'Y' at B. Prove that $∠$ AOB = 90$°$ .

- Jayant SharmaA quadrilateral ABCD is drawn to circumscribe a circle. Prove that AB + CD = AD + BC

- Shalu SinghThe length of a tangent from a point A at a distance 5 cm from the center of the circle is 4 cm. Find the radius of the circle.

- Shalu SinghProve that the tangents drawn at the ends of a diameter of a circle are parallel.

- Shalu SinghFrom a point Q, then length of the tangent to a circle is 24 cm and the distance of Q from the center is 25 cm. Find the radius of the circle.

- Jayant SharmaRecall that two circles are congruent if they have the same radii. Prove that equal chords of congruent circles subtend equal angles at their centers.
