Question

complete this sentence with the best of the choices given. if both pairs of angles are congruent, then a quadrilateral is a parallelogram. after you pick your answer press go. a. inverse b. opposite c. adjacent d. consecutive e. corresponding

Explanation:

According to the properties of parallelograms, one of the key characteristics is that both pairs of opposite angles are congruent.

• Inverse angles: This term is not relevant in the context of parallelogram angle properties.
• Adjacent angles: In a parallelogram, adjacent angles are supplementary (sum to \(180^{\circ}\)), not necessarily congruent.
• Consecutive angles: Same as adjacent angles, they are supplementary, not congruent.
• Corresponding angles: This is a concept mainly used in the context of parallel lines and transversals, not for defining a parallelogram based on its own angle - pair properties.

Answer:

B. opposite
