Question

6. In Fig. 7.21. AC = AE, AB = AD and
Z BAD= Z EAC. Show that BC = DE.​

Answer 1

Answer:

please upload figure

Step-by-step explanation:

figure is not attached

Answer 2

Answer

It is given that angle BAD= angle EAC

angle BAD +angle DAC = angle EAC +angle DAC [add angle DAC on both sides]

: angle BAC = angle DAE

In triangle BAC and triangle DAE

AB= AD (Given)

angle BAC = angle DAE(Proved above)

AC =AE (Given)

: triangle BAC congrunt to triangle DAE (By SAS congruence rule)

:BC = DE (By CPCT)
