Answer:
Given:- △ABC, right angled at C.
Two points D and E are on the sides AC and AB.
To prove:- AE2+BD2=AB2+DE2
Construction:- Join the point D with B and Eand point E with A.
Proof:-
Using pythagoras theorem,
Hypotenuse2=Perpendicular2+Base2
In △ACE,
AE2=AC2+CE2.....(1)
In △BCD,
BD2=DC2+BC2.....(2)
In △ABC,
AB2=AC2+BC2.....(3)
In △DCE,
DE2=DC2+CE2.....(4)
Now,
AE2+BD2=AB2+DE2
AC2+CE2+DC2+B
