Question

prove that triangle ABC is congruent to triangle DCB, if AC = DB and angel A = angle D​

Answer 1

Question ::-

prove that triangle ABC is congruent to triangle DCB, if AC = DB and ∠A = ∠D.

Given ::-

• AC = DB
• ∠A = ∠D

To Prove ::-

• ABC ≅ DCB

Required answer ::-

• AC = DB [Given]

• ∠A = ∠D [Given]

• BC = BC [ both triangles lie on same base ]

By SAS congruence , we proved that ::-

• ∠ABC ≅ ∠DCB
