It is a square, a regular parallelogram with all right angles. The reason is that in a parallelogram, the adjacent angles are supplementary (equal 180 degrees).
In any case, the opposite angle would be 90 degrees as well, leaving just 180 degrees for the other two identical opposite angles.

What are the angles in a parallelogram if the measure of one interior angle is 50 degrees more than 4 times the measure of another angle?
Opposite angles of a parallelogram are equal, and adjacent angles are supplementary. Let one angle be θ, then the adjacent angle is 4θ + 50° → θ + 4θ + 50° = 180° → 5θ = 130° → θ = 26° → The two adjacent angles are 26° and 154°. → The angles of the parallelogram are 26°, 154°, 26°, 154°.
Is it true or false that in a parallelogram the opposite angles are complementary?
Generally false. In a parallelogram, the opposite angles are equal. They could be complementary in a highly skewed parallelogram in which one angle is 45 degrees.
What is the measure of one exterior angle of a decagon?
Each interior angle of a decagon is 144 degrees.An exterior angle is 180 - measure of interior angle.There exterior angle of decagon is 180-144which is equal to-36
If one angle in a parallelogram is it a rectangle?
If you mean if one of the angles is a right angle, then yes, because a rectangle is the only option left if it is to remain a parallelogram.
How many sides does a regular polygon have if the measure of one interior angle is 150?
if the interior angle is 150 the exterior angle equals 30. since exterior angle equals 360/ by number of sides the number of sides equals 360/30 which equal 12
What does a parallelogram rhombus and trapezoid have in common?
Have four sideshave 360 degrees as interior angle sumalso they have one pair of opposite side equal
What are the other angles of a parallelogram when one interior angle is 27.5 degrees?
The other 3 angles are 27.5 degrees, 152.5 degrees and 152.5 degrees because opposite angles are equal in a parallelogram and its 4 interior angles add up to 360 degrees.
What is a parallelogram with equal sides and at least one right angle?
a square
Is a rectangle a parallelogram with a right interior angle?
Yes. If it has ONE right angle, then ALL four angles are right angles.
Parallelogram are what rectangle?
A rectangle is a parallellogram with one right angle; A parallelogram is a quadrilateral with opposite sides equal and parallel.
What are the angles in a parallelogram if the measure of one interior angle is 50 degrees more than 4 times the measure of another angle?
Opposite angles of a parallelogram are equal, and adjacent angles are supplementary. Let one angle be θ, then the adjacent angle is 4θ + 50° → θ + 4θ + 50° = 180° → 5θ = 130° → θ = 26° → The two adjacent angles are 26° and 154°. → The angles of the parallelogram are 26°, 154°, 26°, 154°.
What does one side of a hexagons interior angle equal?
120o
Is a parllelogram a square?
No, but a square is a parallelogram (with one right angle and adjacent sides equal)
A rectangle is a parallelogram with a right interior angle?
Yes, that is what is rectangle is. One can prove that all of the angles are right angles.
Is it true or false that every parallelogram with at least one right angle is a rectangle?
TRUE.A rectangle is by definition a parallelogram. A parallelogram is a quadrilateral with 2 pairs of parallel lines. A rectangle is a parallelogram with 4 equal angles which are 360o/4 = 90o.The opposite angles of a parallelogram are equal as well. Therefore the following is true.If one angle is equal to 90o then the opposite angle is 90o. That leaves two angles and 180o. Since the two angles left are equal then they are each 180o/2 which is also 90o.
Is it true or false that in a parallelogram the opposite angles are complementary?
Generally false. In a parallelogram, the opposite angles are equal. They could be complementary in a highly skewed parallelogram in which one angle is 45 degrees.
Does a parallelogram ever have lines of symmetry?
If one angle is 90o (so that they are all 90o) then it will have at least 2. In other words: A square is a rectangle with equal sides A rectangle is a parallelogram with equal angles.
