Question: Which of the following pairs of triangles are congruent by the ASA criterion?

Options:

1. Angle A = 30°, Angle B = 60°, Side AB = 5 cm
2. Angle A = 30°, Angle B = 60°, Side AC = 5 cm
3. Angle A = 60°, Angle B = 30°, Side AB = 5 cm
4. Angle A = 60°, Angle B = 30°, Side AC = 5 cm

Correct Answer: Angle A = 30°, Angle B = 60°, Side AC = 5 cm

Solution:

For ASA, two angles and the included side must be equal. The second option meets this criterion.
