One of the angles of a parallelogram measures 63°. Measures of the other three angles of the parallelogram are
63°, 63°, and 63°, because all the angles of a parallelogram are always congruent.
63°, 27° and 27°, because consecutive angles of a parallelogram are complementary and the sum of the measures of the angles of a parallelogram is 180°.
63°, 117° and 117°, because consecutive angles of a parallelogram are supplementary and the sum of the measures of the angles of a parallelogram is 360°.
