Question

∆ is an isosceles triangle with AC = BC. If ^2 = 2^2 , then find ∠ . plz write full sum​

Answer 1

Answer:

Step-by-step explanation:

In an isosceles triangle ABC, if AC=BC and AB² = 2(AC)², then the measure of angle C will be... This is the Question.

And here's the solution

In △ABC

(AB)² = 2(AC)²

(AB)² = (AC)²+ (AC)²

∵AC = BC

(AB)² = (AC)²+ (BC)², This equation comes out as Property of Right angle traingle or also known as Pythagoras theorem.

∴∠C=90°

And △ABC is a right angle triangle.
