Two parallel lines are cut by a transversal. If one interior alternate angle is 58°, what is the other alternate angle?

Answer and explanation

Correct answer: B. 58°

  1. Step 1: Alternate interior angles between two parallel lines cut by a transversal are equal. Step 2. Therefore, the other alternate interior angle is exactly 58°. Answer: 58°. Why not the others: 32° is the complement (90° - 58°); 122° is the supplementary interior angle (180° - 58°); 148° is an arithmetic error.
