[" Q1.In the Dig ABC is a triamgle in which "2BAC=],[30^(@)" .Show that "BC" is equal to the radius of the "],[" circumcisucte of "/_ABC" ,whose centre is "0" ."]

In the given figure , ABC is a triangle in which angle BAC = 30 ^(@) . Show that BC is equal to the radius of the circumcircle of the traiangle ABC , whose centre is O.

ABC is a triangle in which angleBAc = 30^@ . Prove that BC is the radius of the circumcircle of triangleABC , whose centre O.

In the adjacent figure, ABC is a triangle in which angle ABC AC^2 = AB^2 + BC^2 -2BC. BD .

In Delta ABC, O is the circum centre of the circle. If angle OBC = 37^(@) then angle BAC is equal to :

In the adjoining figure, ABC is a triangle in which AD is the bisector of /_ A . If AD bot BC , show that /_\ ABC is isosceles.

In the given figure ABC is a right triangle and right angled at B such that /_BCA = 2/_BAC. Show that hypotenuse AC = 2BC.

In the given figure ABC is a right triangle and right angled at B such that /_BCA = 2/_BAC. Show that hypotenuse AC = 2BC.

In the given figure ABC is a right triangle and right angled at B such that /_BCA = 2/_BAC. Show that hypotenuse AC = 2BC.

In the given figure ABC is a right triangle and right angled at B such that /_BCA = 2/_BAC. Show that hypotenuse AC = 2BC.
