Question

one angle in one triangle is congruent to one angle in another triangle.what can you conclude about the other two angles in both triangles?

Answer 1

triangles are congruent, not angles, so I'm not sure if you've posted the question correctly. Angles are equal ( or not!)
if the angles in two triangles are equal, the only conclusion you can draw is that the sum of the remaining angles from the first triangle equals the sum of the remaining angles from the second triangle.
