We are here given that BD and AC bisect each other. Therefore ,
Again here , angle AEB and angle DEC are vertically opposite angles . So they will be equal.
Therefore in ∆ABE and ∆CDE ,
- BE = DE ( given)
- AE = EC ( given)
- ang. AEB = ang. DEC ( v.o.a)
Therefore by SAS congruence condition ,
- ∆ABE
∆CDE
Hence proved!
