LOL, yes, just use a square

To find the sum of the interior angles of a quadrilateral, you need to know that a quadrilateral has four sides and four angles.

To find the sum, you can use the formula:
Sum of interior angles = (n-2) * 180,

where n represents the number of sides in the shape.

In this case, for a quadrilateral, n = 4.
So, the sum of the interior angles of a quadrilateral is:
Sum = (4-2) * 180 = 2 * 180 = 360.

Therefore, the correct answer is 360.
