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°.
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.
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 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.
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
Have four sideshave 360 degrees as interior angle sumalso they have one pair of opposite side equal
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.
Yes. If it has ONE right angle, then ALL four angles are right angles.
a square
A rectangle is a parallellogram with one right angle; A parallelogram is a quadrilateral with opposite sides equal and parallel.
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°.
Yes, that is what is rectangle is. One can prove that all of the angles are right angles.
120o
No, but a square is a parallelogram (with one right angle and adjacent sides equal)
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.
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.
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.
