Theorem:
The tangents to a circle from an external point are equal.
ASSIGNMENT
1.O is the centre of a circle and two tangents from a point T touch the centre at A and B. BT is produced to C. If <AOT = 670.calculate < ATC.
2.AD is a diameter of a circle,AB is a chord and AT is a tangent. a) State the size of <ADBb)If BAT is an acute angle of x0,find the size of DAB in terms of x.
