Question

corresponding angles formed by two parallel lines intersected by a transversal are always:
○ congruent.
○ obtuse.
○ supplementary
○ complementary.
○ acute.

Explanation:

To solve this, we recall the properties of corresponding angles formed by parallel lines and a transversal. By the Corresponding Angles Postulate, when two parallel lines are cut by a transversal, corresponding angles are congruent. Obtuse (greater than 90°), acute (less than 90°), supplementary (sum to 180°), or complementary (sum to 90°) do not always describe corresponding angles. For example, corresponding angles can be acute or obtuse, but they are always congruent.

Answer:

A. congruent
