Question

ABC is an iscocles right angled triangle at C find the (AB)^2​

Answer 1

Answer:

draw the triangle that vin right angled into 90 degree

Answer 2

⭐Given data :

Δ ABC is a right Δ and also isosceles triangle.,  

⭐ To prove:

 AB^2 = 2 AC^2

Step 1:

Proof:

       Here,  

                Hypotenuse = AB

Also, as it is given that, ΔABC is isosceles,  

Step 2:

AC = BC   [equal sides of isosceles Δ]  

Using Pythagoras theorem,  

Step 3:

In Δ ABC, we have ;

AB^2 = AC^2 + BC^2

as AC = BC

therefore :-

       AB^2 = 2 AC^2 = 2 BC^2

thus,

         AB^2 = 2 AC^2

   

hence you answer  is 2 *AC^2   .
