in isosceles triangle ABC, if AC=BC and AB2=2AC2 then the measure angC

1.	in isosceles triangle ABC, if AC=BC and AB2=2AC2 then the measure angC ???
Answer» C= 90° Much bmdbmn Triangle ABC is Isoscelesand it is givenAC = BCAB² = 2 AC²= AC² + AC²AC = BC so we can write,AB² = BC² + AC²This is similar to Pythagoras TheoremAB = hypotenuseBC = Perpendicular or BaseAC = Base or PerpendicularThereforeC = 90°
