In an isosceles Delta ABC , if AC=BC and AB ^(2)= 2AC^(2) "then" angle C=?

In an isosceles Delta ABC , if AC=BC and AB ^(2)= 2AC^(2) then angle C=?

in Delta ABC,/_A=2/_B Prove that BC^(2)=AC^(2)+AC.AB

A statements of Assertion (A) is followed by a statement of Reason (R ). Mark the correct choice as. Assertion (A): ABC is an isoseles triangle right triangle , right angled at C. Then AB^(2) = 3AC^(2) . Reason (R ): In an isosceles triangle ABC if AC = BC and AB^(2) = 2AC^(2) then angle C = 90^(@) .

In triangle ABC , /_B=90^@ and AB = BC. If AC = 2sqrt2 , then find AB and BC.

In Delta ABC, if AB=AC and /_A=50^(@), then /_C=

In Delta ABC, if AB=AC and /_A=50^(@), then /_C=

In Delta ABC,/_A=100^(@) and AB=AC. Find /_B and /_C

In Delta ABC , if /_A=80^(@) and AB=AC , then /_ B = ___________________ .

ABC is an isosceles triangle of which AC=BC and AB^(2) = 2AC^(2) . Then value of /_C will be -
