Final answer:
If the fractions a/b and c/d are equal, the pair of angles that are congruent are the ones formed by the same numerators and denominators.
Step-by-step explanation:
If the fractions are represented as a/b and c/d, the pair of angles that are congruent are the ones formed by the same numerators and denominators.
In other words, if a = c and b = d, the angles are congruent. For example, if a/b = 2/3 and c/d = 2/3, then the angles formed are congruent.
