kite
Each interior angle of a regular polygon of n sides (n ≥ 3) contains
4n right angles
2(n + 1)/n right angles
2(n - 1)/n right angles
2(n - 2) /n right angles
The sum of the angles of a hexagon is
360°
540°
720°
810°
One of the angles of a parallelogram measures 63°. Measures of the other three angles of the parallelogram are
63°, 63°, and 63°, becasue all the angles of a paralleolgram 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°.
Cannot be determined
