Using the given figure, let's state the theorem which defines the congruency of both triangles.
Let's first label the triangles:
From the figure above, we now have two triangles:
Triangle ABC and Triangle CDA.
From the triangles we have the congruent sides:
AB ≅ CD
We have the congruent angles:
∠BCA ≅ ∠DAC
Also, using the reflexive property, AC ≅ AC.
Now, we have two pairs of congruent sides and one pair of non-included congruent angle.
Since we have two pairs of congruent sides and the pair congruent angles are not included we cannot prove the triangles are congruent.
Therefore, we can say the triangles are NOT CONGRUENT
ANSWER:
Not congruent.
