and sum of all angles in a quardilateral is 360degrees

Here are a few of many theorems that you'll use in geometry to determine a specific quadrilateral:Opposite angles of a parallelogram are equal.If the diagonals of a quadrilateral bisect each other, then it is a parallelogram.The diagonals of a rectangle are equal.The diagonals of a rhombus are perpendicular to one another.By the way, a square has all the properties of the parallelogram and the rectangle and the rhombus; it's a quadrilateral with all right angles and all equal sides!
