Question

Are the two diagonals of a rectangle equal ? why?​

Answer 1

Answer:

Yes, They are Equal

Step-by-step explanation:

Rectangle has opposite sides equal and all angles are 90°

Let's Take,

Length = l

Width = w

Diagonal = d

So by Pythagoras Theorem,

l² + w² = d₁²

l² + w² = d₂²

⇒ d₁² = d₂²

⇒ d₁ = d₂
