Answer:
SSS
Step-by-step explanation:
the triangles would be proven congruent by SSS
AC is equal AC because of the reflexive property (it is equal to itself).
Answer:
We used SSS rule of congruence to prove that the triangles are congruent.
Step-by-step explanation:
We are given the following information in the question:
AB = CD
BC = DA
We have to prove that
[tex]\angle B = \angle D[/tex]
We will first prove the congruency of triangle.
[tex]\text{In }\triangle ABC \text{ and } \triangle CDA[/tex]
AB = CD ( Given )
BC = DA ( Given )
AC = CA (Common )
Hence, [tex]}\triangle ABC \cong \triangle CDA[/tex] by SSS rule of congruence( Side Side Side).
Since the triangles are congruent, [tex]\angle ABC = \angle CDA[/tex]
