Abc Is Isosceles Triangle With Ac Bc If Ab2 2ac2

ABC is an isosceles triangle with AC = BC. If AB2 – 2AC2, prove that ABC is a right triangle


Given that,


 ABC-AC2 + AC2

AB2 = AC2 + BC2 (As, AC = BC)

The triangle is satisfying the Pythagoras theorem

Therefore, the given triangle is a right-angled triangle
