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.
Protractor
A protractor is normally used to construct angles.
you might not be able to construct all the angles, but using a compass you can construct some angles by constructing angular bisectors. eg:construct angular bisector of straight line i.e; 180 degrees it gives 90 degrees
By drawing regular polygons as for instance a square will have 4 equal right angles and an equilateral triangle will have 3 equal 60 degree angles.
Construct an equilateral triangle because each of its 3 exterior angles measures 120 degrees
It is done out using a protractor.
Using the formula: (number of sides -2)*180 = sum of interior angles
The sum of the angles in a quadrangle is 360 degrees, whatever the side lengths.
The answer depends on what information is available but there is no simple solution. Using a protractor seems the best bet.
You can onlymeasure angles by using a protractor.
If, by quadrangle, you mean quadrilateral (four sided figure), than the angles add to 360 degrees. You can figure out the degree measure for any sided figure by simply letting the number of sides equal the variable n, and using the equation 180(n-2) (one hundred eighty times n minus 2). This works for any figure.

A protractor is normally used to construct angles.
To accurately measure angles using a protractor, place the center of the protractor on the vertex of the angle. Align one side of the angle with the zero line on the protractor. Read the measurement where the other side of the angle intersects the protractor scale.
Using a protractor is the simplest way of solving the measurements of angles.
