Depends on your question. A rectangle is a parallelogram and has 4 right angles. BUT A parallelogram can have only a total of one, two, or four right angles. Mathematically, 3 right angles is 270 degrees. A parallelogram has 360 degrees. 360 - 270 = 90 degrees = right angle.
Draw any square or rectangle, and you have it.
A rhombus, an equal sided parallelogram or an equal sided quadrilateral with no right angles.
It is a parallelogram with 4 right angles and it has congruent diagonals that bisect.
Any shape with more than 3 sides can have two pairs of equal sides and no right angles. If it only has 4 sides in total and isn't a parallelogram, then it's a trapezoid.
Being a quadrilateral, the sum of all four angles is 360o.Opposite angles of a parallelogram are equal.Adjacent angles of a parallelogram are supplementary, that is add to 180o.Given one angle of a parallelogram, the other 3 angles can be calculated:the opposite angle is the same;the other two angles are the same as each other and are 180o - the_given_angle
A parallelogram has 4 sides and 4 angles that add up to 360 degrees whereas a triangle has 3 sides and 3 angles that add up to 180 degrees.
Triangle has 3 angles adding to 180 degrees Parallelogram has 4 angles adding to 360 degrees Pentagon has 5 angles adding to 540 degrees Heaxagon has 6 angles adding to 720 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.
Yes, a trapezoid can have 3 right angles.
