JudySince every rectangle has 4 internal 90-degree angles ("right angles"), the sum of the angles of any rectangle is 90o+90o+90o+90o, equaling 360 degrees.

Sum of measures of angles of a triangle to sum or measures or angles of a rectangle?
The sum of the internal angles of any triangle is 180 degrees. Any rectangle has four 90 degree internal angles, totalling 360 degrees.
What is the sum of the angles of a square?
The interior angles of a square or any rectangle add up to 360 degrees.
Are consecutive interior angles of a rectangle are supplementary?
Yes. Two angles are suplementary if their sum is 180 degrees. All interior angles in a rectangle are 90 degrees, so any pair of these angles is supplementary.
How do you find the sum of the angles in a quadrangle without using a protractor?
Assuming it is a four sided closed figure, the sum of the angles is always 360 degrees. For example, a rectangle has four sides with each angle equal to 90 degrees. If you add each of the angles together you come up with the sum of the angles totaling 360 degress.
Is all rectangles cyclic?
as the sum of opposite angles of a rectangle always equals 180 degrees all rectangles are cyclic Actually a rectangle is only cyclic when the product of the diagonls equals the sum of opposite pairs of sides.
