Formula Used/Theory:-

⇒ If hypotenuse and 1 sides of Right angled triangle are equal in both the triangles then both triangles are congruent by RHS congruence criterion

In ∆ABC and ∆EOD

As ∆ABC, ∆EOD both are right angled triangle

Right angled at ∠ABC and ∠EOD

∠B = ∠O = 90°

AC = DE (Hypotenuse Given)

AB = EO (Given)

∆ABC ≅ ∆EOD

Hence; both triangles are congruent by RHS criterion
