If AB is chord of a circle with centre O, AOC is a diameter and AT is the tangent at A as shown in figure. Prove that `angleBAT=angleACB.`

AB is a chord of a circle with centre O, AC is a diameter and AT is the tangent at A as shown in the figure. Prove that angleBAT=angleACB .

In fig AB is chord of a circle with centre O and AP is the tangent at A such that angleBAP = 75^@ find angleACB

AB is a diameter and AC is a chord of a circle with centre O such that angleBAC=30^@ . The tangent at C intersects AB at a point D. Prove that BC=BD.

AB is a chord of a circle with centre O and diameter 20 cm. If AB = 12 cm, find the distance of AB from O.

AB is a chord of a circle with centre o and diameter 20 cm. If AB = 12 cm, find the distance of AB from O.
