Answer 1

Answer:

mark the point of intersection of EA &DC as O

Step-by-step explanation:

I'll be referring to angle as "a"

a EOC = a DOA

prove triangle EOC and DOA congruent and hence proved

Answer 2

Step-by-step explanation:

Given: angle x=angle y, AB=CB

To prove:AE=CD

Proof:

In ∆ABE & ∆CBD

AB=CB(given)

angle B=angle B(common)

angle x=angle

Therefore, angle x=angle DCB

angle y=angle EAB(interior opp.angles)

so,angle DCB=angle EAB

Therefore, ∆ABE is congruent to ∆CBD

Thus,AE=CD(by c.p.c.t.c)
