The answer is below
Explanation:
Two triangles are said to be equal if all their three sides and all their three angles are exactly equal to each other.
Given triangle ABC and Triangle DCB, we can see that:
∠A = ∠D, |AB| = |CD|, |AC| = |BD| and they share the same side BC. Hence:
a) By the side-side-side (SSS) triangle congruence theorem the two triangles are equal. i.e. |AB| = |CD|, |AC| = |BD| and they share the same side BC.
b) By the side-angle-side (SAS) triangle congruence theorem the two triangles are equal. i.e. |AB| = |CD|, |AC| = |BD| and ∠A = ∠D.
