Question

AB=DC and AC=BD in the above figure​

Answer 1

Step-by-step explanation:

a) triangle ABC =triangle CDB

because :- AB = DC

angle ABC = angle DCB (VOA)

BC=BC

so, SAS the triangles are congruent

b. DB=AC

angle ABC = angle DCB

BC=BC

c. yes triangle ABC is congruent to triangle DBC

hope it helps

Answer 2

Answer:

1. yes

2. Given below

3. Yes

Step-by-step explanation:

● In the ∆ABC & ∆CDB,

AB = CD (Given) (S)

BC = BC (Common side) (S)

there fore,

Angle ABC = Angle DCB (A)

Hence ∆ABC is congruent to ∆CDB.
