Ninety Degrees
90°
it measures 360 degrees
A square has four angles. Each of these angles measures 90 degrees, making the total sum of the angles in a square 360 degrees.
A parallelogram has four angles. The opposite angles are equal, and the adjacent angles are supplementary, meaning they add up to 180 degrees. Therefore, if one angle measures ( x ) degrees, the opposite angle also measures ( x ) degrees, while the other two angles measure ( 180 - x ) degrees each.
Spheres are measured with solid angles (which are like two dimensional angles). These angles can be measure with square degrees or steradians. A sphere measures 129300/π square degrees (or about 41,253 square degrees). A sphere measures 4π steradians (or about 12.566 steradians.)

3 interior angles and each of them measures 60 degrees
Supplementary angles are 2 angles that add up to 180°. Complementary angles are 2 angles that add up to 90°.

A 'right angle' looks like a corner, and measures 90 degrees.
A quadrilateral doesn't have degrees. It has four sides, four inside angles, four outside angles, a perimeter, and an area. If you add up the measures of all four outside angles, they add to 360 degrees. If you add up the measures of all four inside angles, they add to 360 degrees too.
There would be twelve angles in all: six each of two complementary measures (or 12 right angles).
13 sides
A pentagon has five angles. Each interior angle of a regular pentagon measures 108 degrees, and the sum of all the interior angles in any pentagon is 540 degrees.
