Please ask one question at a time.
The answers to your first two questions are as follows:
1)
2)
Draw a circle with a bangle (the centre is unknown). Let P be a point outside a circle.
Required : To draw tangents from a point P outside the circle.
Steps of construction:
i. Draw a secant PAB to intersect the circle at A and B.
ii. Produce AP to a point C, such that PA = PC.
iii. With BC as a diameter, draw a semicircle.
iv. Draw PO ^ CB, intersecting the semicircle at O.
v. Taking PO as radius and P as centre, draw arc to intersect the circle at T and T.
vi. Join PT and PT. Then PT and PT are the required tangents.
