The 4 interior angles of any quadrilateral always add up to 360 degrees

No, a quadrilateral couldn't have four obtuse angles because the four interior angles of a four-sided quadrilateral add up to 360 degrees, and the sum of the measures of four obtuse angles would be greater than 360 degrees.

A quadrilateral is a shape with four sides... It doesn't have *one* angle. The sum of the interior angles of a quadrilateral will always be 360 degrees, however, it is impossible to know the value an individual angle of a quadrilateral with the information given.

A quadrilateral has four angles. There are always the same number of angles as there are sides, so since a quadrilateral has four sides it must also have four angles.A quadrilateral doesn't "do" any angles. However, it has four angles. (If that is what you wanted to know.)

There are four angles in a trapezoid since a trapezoid is a quadrilateral. A quadrilateral has four sides and four angles.
