360 degrees.
The answer depends on what it is that is being summed: the length of the sides or diagonals, the angle measures, something else.
a quadrangle with only one right angle
There are a number of ways of proving that the sum of the interior angles of a polygon, which has n sides, is (n - 2)*180 degrees.In the case of a quadrangle, n = 2 and so the angle sum is (4 - 2)*180 = 2/180 = 360 deg.
how do you draw a quadrangle that has at least 1 right angle.
360
The sum of the angles in a quadrangle is 360 degrees.
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.
There is no specific name for such a quadrangle.
I'm guessing a right-angled quadrangle.
