Two circles touch each other internally. Show that the tangents drawn to the 2 circles from any point on the common tangent are equal in length.
Calculate the length of a direct common tangent of two circles of radii 3cm and 8cm with thier centres 13cm apart????
find the centre of circle by construction using only 60-30 setsquares and a pencil
3 circles touch each other externally. A triangle is formed when the centres of these circles are joined togethe. Find the radii if the circle if the sides of the triangle formed are 6cm, 8cm and 9 cm.
PQ is a chord of length 8 cm of a circle of radius 5 cm. The tangents at P and Q intersect at a point T. Find the length TP
In a circle I is the incentre of triangle ABC, BI when produced meets the circumcircle of triangle ANC at D.

Calculate:-
i) Angle DCA
ii)Angle DAC
iii) Angle DCI
iv) Angle AIC
The length of common chord of two intersecting circles is 30 cm. If the diameters of these two circles be 50 cm and 34 cm, calculate the distance between their centres.
D and E are points on equal sides AB and AC of an isoscles triangle ABC such that AD - AE. Prove that the points B, C, E, D are concyclic.
prove that any four vertices of a regular pentagon are concyclic(lie on the same circle).
