In the figure,tangents at B and C of the circle with centre O intersect at point A. If `/_BAC = 90^(@)` then prove `square `BACO is a square

In Figure, B C is a tangent to the circle with centre OdotO E bisects A Pdot Prove that A E O ~ A B Cdot

In Figure,two tangents ABandAC are drawn to a circle with centre O such that /_BAC=210^(0) .Prove that OA=2AB

In the figure, PO_|_QO. The tangents to the circle with centre O at P and Q intersect at a point T. Prove that PQ and OT are right bisectors of each other.

In Figure, two tangents A Ba n dA C are drawn to a circle with centre O such that /_B A C=120^0dot Prove that O A=2A B

In Figure 2, AB and AC are tangents to the circle with centre O such that angle BAC = 40°. Then angle BOC is equal to

In Figure,O is the centre of the circle.Find /_BAC
