Question

prove that the triangles are congruent if AC=DF​

Answer 1

AnswEr :

In the given figure,

• AC = DF

• ∠A = ∠D

• ∠C = ∠F

•°• ∆ABC ≅ ∆DEF⠀⠀(by ASA congruence rule)

⠀⠀⠀⠀⠀⠀⠀Hence, proved!

━━━━━━━━━━━

Rules for congruency :

• SSS – Side-Side-Side

• SAS – Side-Angle-Side

• ASA – Angle-Side-Angle

• AAS – Angle-Angle-Side

Two triangles are congruent if and only if they've exactly the same shape and same size.
