The sum of all angles in a quadrilateral is equal to _________ right angles.A. 2B. 3C. 4D. 360

The sum of all angles in a quadrilateral is always 360 degrees. This is a fundamental property of quadrilaterals, as the sum of the interior angles of any polygon can be calculated using the formula:

Sum of interior angles = (n - 2) × 180 degrees, where n is the number of sides.

For a quadrilateral, n = 4, so:

Sum of interior angles = (4 - 2) × 180 = 2 × 180 = 360 degrees.

Since one right angle is 90 degrees, 360 degrees equals 4 right angles.

Therefore, the correct answer is:

D. 360
