Find the side AB .

Question 2 :
From an external point P, two tangents, PA and PB are drawn to a circle with centre O. At one point E on the circle tangent is drawn which intersects PA and PB at C and D, respectively. If PA = 10 cm, what is the perimeter of the triangle PCD?

Question 3 :
The lengths of tangents drawn from an external point to a circle are equal . TRUE or FALSE ?

Question 4 :
Two concentric circless are of radii 5 cm and 3 cm. Find the length of the chord of the larger circle which touches the smaller circle

Question 5 :

Then the radius of the circle is
