Yes
any closed figure made up of 4 straight sides.
a quadrilateral
They sides if a quadrilateral can add up to anything but the angles have to equal 360
Because there are 180 degrees in a triangle and a 4 sided quadrilateral is made from two triangles so therefore 2*180 = 360 degrees
A quadrilateral (a 2-D figure made up of four sides) can be made up of any number of smaller shapes, including rectangles. In fact, a rectangle IS a quadrilateral.

a quadrilateral
A quadrilateral is a polygon made up of four "sides" or edges and four vertices and corners. So basically it has four sides no matter what shape. Here's some shapes: Parallelogram, butterfly, rectangle, kite, rhombus, and square.
They sides if a quadrilateral can add up to anything but the angles have to equal 360
Not necessarily. A quadrilateral is made up of 4 sides but they don't have to be the same. Some, like a square and a rhombus, have equal sides but a trapezium can have 4 different sides.
Because there are 180 degrees in a triangle and a 4 sided quadrilateral is made from two triangles so therefore 2*180 = 360 degrees
All four of the interior angles of a quadrilateral add up to 360 degrees.
The 4 interior angles of a quadrilateral add up to 360 degrees
The four angles of a quadrilateral add up to 360 degrees.
