Fill in the blanks: The common point of a tangent and the circle is called...... A circle may have ..... parallel tangents. A tangent to a circle intersects it in ..... point(s). A line intersecting a circle in two points is called a ........ (v) The angle between tangent at a point on a circle and the radius through the point is .........

In a circle, PQ and RS are two parallel tangents at A and B. The tangent at makes an intercept DE between PQ and RS. Then angle DOE is equal to : (where O is centre).

Point O is the centre of a circle . Line a and line b are parallel tangents to the circle at P and Q. Prove that segment PQ is a diameter of the circle.

Fill in the blank : From a point on a circle ............. Tangent (s) can be drawn.

Prove that a diameter AB of a circle bisects all those chords which are parallel to the tangent at the point A.

Given two concentric circles of radii r and 2r two parallel tangents to the inner circle cut off an arc from the outer circle,find its length.

Two circles have an external tangent with length 36cm. The shortest distance between these circles is 14cm. If the radius of the longer circle is 4 xx the radius of the smaller circle then the radius of the larger circle in cms is

How many parallel tangents can a circle have ?
