A boy is cycling such that the wheels of the cycle are making 140 revolutions per minute. If
prove that line segment joining the points of contact of two parallel tangents is the diameter of the circle
Prove that the angle between two tangents drawn from an external point to a circle is
supplementary to the angle subtended by the line segment joining the points of contact at the centre.
PQL and PRM are tangents to the circle with centre o at the points Q and R ,respectively and S is a point on the circle such that angle SQL=50 and angle SRM=60. Find angle QSR.
The tangent at a point C of a circle and diameter AB when extended intersect at P. If PCA=1100 , find CBA.6. The tangent at a point C of a circle and diameter AB when extended intersect at P. If PCA=1100 , find CBA.
