Question

Given: JIKL is a quadrilateral with angle measures as shown.KDi120"60"Which is true about quadrilateral JIKL?Quadrilateral JIKL is a parallelogram.If mZK = 120, then Quadrilateral JIKL is a parallelogram.O if IK || JL, then quadrilateral JIKL is a parallelogram.O If IJ || KL, then quadrilateral JIKL is a parallelogram.

Answer 1

one of the coditions for a quadrilateral to be a patrallelogram is if and only if two paira of oppositw sied are parallel (by definition),the two pairs of opposite sides are equal in length. Two pairs of opposite angles are equal in measure.

so,

with all this said,

since IJ is parallel to KL, then the quadrilateral is a parallelogram

so the last option is correct
