Problem
If a quadrilateral is a trapezoid, which statements must be true? Check all that apply.
Answer
C, D, F
Step-by-step solution
A trapezoid has at least one pair of parallel sides. In trapezoid JKLM, KL is parallel to JM. Consecutive angles between the parallel sides are supplementary. Therefore, angle J and angle K are supplementary, and angle L and angle M are supplementary. If it is an isosceles trapezoid, then base angles are congruent.
