Triangles ABC and CDA are congruent.
Which angle is equal to angle BAC?
We observe the order of the letters in the congruent triangles and write the matches (from left to right).
That is:
Angle A is equal to angle C.
Angle B is equal to angle D.
Angle C is equal to angle A.
From this, it is deduced that angle BAC (where the letter A is in the middle) is equal to angle C — that is, to angle DCA (where the letter C is in the middle).
