Nadusha1986 [10]

Answer:

O A.

Step-by-step explanation:

<u>Option B</u> identifies two sides and the angle not between them. The two triangles will be congruent in that case only if the angle is opposite the longest side, which is <u>not true</u> in general.

<u>Option D</u> identifies three congruent angles, which will prove the triangles similar, but not necessarily congruent.
