- How many tangents can a circle have ?
- A tangent PQ at a point P of a circle of radius 5 cm meets a line through the centre O at a point Q so that OQ = 12 cm. Length of PQ is : (A) \( 12 \) cm (B) \( 13 \) cm (C) \( 8.5 \) cm (D) \( \sqrt{119} \) cm
- Draw a circle and two lines parallel to a given line such that one is tangent and the other, a secant to the circle.
