If the question is, what is the sum of the angles of a quadrangle, then the answer is 360 degrees.Quadrangle is another name for quadrilateral. A quadrangle alone cannot assume a sum of any sort, but the length of its sides or the measurement of its angles can.

i don't know it this helps, but the sum of the angles in a quadrangle is 360 !

The sum of the angles in a quadrangle is 360 degrees, whatever the side lengths.

If a circle (equalling 360 degrees) is cut into four pieces, then rearranged a bit, it will become to look like one quadrangle or another. That is why a quadrangle, no matter HOW messed up, will still equal 360 degrees when its angles are added up.

The sum of all four angles inside any 4-sided figure is always 360 degrees.

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.

If both angles are 180, their sum is 360!If both angles are 180, their sum is 360!If both angles are 180, their sum is 360!If both angles are 180, their sum is 360!

The sum of the interior angles is 360 and the sum of the exteriors is 360 also.

360 degrees.

2*pi radians (360 degrees).

Sum of the exterior angles is 360 degrees. So the sum of the interior angles must be 3*360 = 1080 degrees.

It can be proven that the angle sum of a triangle is 180 degrees using Euclid's parallel postulate. Any quadrilateral can be divided into two triangles by connecting two opposite sides. The sum of the angles of the quadrilateral will be the sum of the sum of the two triangles, or in other words 2*180=360. In fact, any n-gon can be divided into n-2 triangles and the sum of the angles of the n-gon will be (n-2)*180.

The exterior sum of angles for any polygon is always 360 degrees.The sum of the exterior angles of a 12 sided dodecagon is 360 degrees

360 degress which is the same as the sum of the interior angles of a quadrilateral. 360 + 8 x 180 = 1800°

the sum of the angles of a trapizoid equal 360 degrees.

The sum of the interior angles is 360.

The sum of all four angles is 360 degrees. Thus, you have insufficient information to know the individual angles; you can only know their sum, which is 360 minus the sum of the other two angles.

-- The sum of the four exterior angles is 360 degrees. -- The sum of the four interior angles is also 360 degrees. -- So the sum of all the interior and exterior angles is 720 degrees.

The interior angles sum to 360 degrees; the exterior angles also sum to 360 degrees.
