Fill the blank: Atmost ______ tangent can drawn from any point on the circle.

Only three tangents can be drawn from a external point of a circle.

Only "________" tangent can be drawn at any point on the circumference of a circle.

Write True or False: Two tangents can be drawn from any external point to a circle.

Tangent is drawn at any point (x_1, y_1) other than the vertex on the parabola y^2=4a x . If tangents are drawn from any point on this tangent to the circle x^2+y^2=a^2 such that all the chords of contact pass through a fixed point (x_2,y_2), then

O is the centre of a circle. An external point P is 26 cm away from the centre of the circle and the length of the tangent (PT) drawn from the point P to the circle at T is 10 cm. Calculate the length of the diameter of the circle.

Find the lengths of the tangents drawn from the point. (-4,5) to the circle x^(2)+y^(2)=16

Find the lengths of the tangents drawn from the point. (-1,1) to the circle x^(2)+y^(2)-2x+4y+1=0

Find the lengths of the tangent drawn from the point. (2,-2) to the circle 3(x^(2)+y^(2))-4x-7y=3

Find the equations of the tangents drawn from the point A(3, 2) to the circle x^2 + y^2 + 4x + 6y + 8 = 0

Fill in the blanks A tangent from an external point A' touches the circle with centre O is B. If OB = 5cm, OA = 13 cm, then the length of AB is_______.
