Question

in an isosceles triangle ABC if AC=BC and AB2=2AC2, then angle C is equal to ??

Answer 1

Answer:

C = 90°

Step-by-step explanation:

Triangle ABC is Isosceles

and it is given

AC = BC

AB² = 2 AC²

= AC² + AC²

AC = BC so we can write,

AB² = BC² + AC²

This is similar to Pythagoras Theorem

AB = hypotenuse

BC = Perpendicular or Base

AC = Base or Perpendicular

Therefore

C = 90°

Answer 2

Answer:

90 degree
