Question

question 2 of 10 if two opposite sides of a quadrilateral are perpendicular and congruent, then the quadrilateral is a parallelogram. a. true b. false

Explanation:

A parallelogram requires opposite sides to be parallel (and congruent). If two opposite sides are perpendicular, they aren't parallel (since parallel lines have the same slope, perpendicular lines have slopes that are negative reciprocals). So having two opposite sides perpendicular and congruent doesn't satisfy the parallelogram definition.

Answer:

B. False
