4. Justify Reasoning Determine whether each statement is always, sometimes, or never true. You may draw a picture of each situation to help you. Explain your reasoning. The first one is done for you. If quadrilateral RSTU is a parallelogram, then RSST. Sometimes; opposite sides of a parallelogram are congruent, but consecutive sides may or may not be congruent If a parallelogram has a 30 angle, then it also has a 150 angle. If quadrilateral GHJK is a parallelogram, then GH is congruent to JK. In parallelogram ABCD, LA is acute and ZC is obtuse. In parallelogram MNPQ, the diagonals MP and NQ meet at R with MR = 7 cm and RP = 5 cm.
