- In the adjoining figure I and II, are circles with P and Q respectively, The two circles touch each other and have common tangent that touches them at points R and S respectively. This common tangent meets the line joining P and Q at O. The diameters of I and II are in the ratio 4 : 3. It is also known that the length of PO is 28 cm. Find the length of SO
- Prove that the perpendicular at the point of contact to the tangent to a circle passes through the centre.
- Two circles with radii a and b touch each other externally. Let c be the radius of circle which touches this circles as well as the common tangent to the circles.Prove that 1/rootc=1/roota+1/rootb.
