3) The number of tangents that can be drawn to a circle at a point on the circle is.

The maximum number of tangents that can be drawn to a circle from a point outside it is…………..

Show that the number of tangents that can be drawn from the point (5/2,1) to the circle passing through the points (1,sqrt(3)),(1,-sqrt(3)) and (3,-sqrt(3)) is zero.

The number of tangents which can be drawn from the point (2, 3) to the circle x^2 + y^2 = 13 are (A) 2 (B) 3 (C) 1 (D) 4

The number of real tangents that can be drawn from (2, 2) to the circle x^(2)+y^(2)-6x-4y+3=0 , is

Consider the relation 4l^(2)-5m^(2)+6l+1=0 , where l,m in R The number of tangents which can be drawn from the point (2,-3) to the above fixed circle are

From an external point P, tangents PA and PB are drawn to a circle. CE is a tangent to the circle at D which intersect PA and PB at point E and C respectvely. If AP=15 cm, find the permeter of the trianglePEC.

From an external point P, two tangents, PA and PB are drawn to a circle with centre 0. At one point E on the circle tangent is drawn which intersects PA and PB at C and D, respectively. If PA=10 cm, find the perimeter of the triangle PCD.

How many chords can be drawn through 21 points on a circle?

To construct the tangents to a circle from a point outside it.

Two circles touch each other internally. Show that the tangents drawn to the two circles from any point on the common tangent, are equal in length.
