Question

If three angles of a triangle are given equal to corresponding angles of another triangle can the triangles be congruent? What else information is required, so that the two triangles are congruent always.

Answer 1

Corresponding Sides are required so that the 2 triangles are congruent always.
because if only angles are same then the length of side would differ and to be congruent triangles require same length of side and same measure of angle. that is why length of side is required to make a triangle completely congruent...
