parallelogram
12 vectors, unless it is a parallelogram (13 if you include the null vector). If the quadrilateral is a parallelogram there will be two fewer.
It could be a triangle, a quadrilateral, a pentagon, a hexagon or even an octagon if they are two concave quadrilaterals.
It is called a polygon. * * * * * Yes, but only if they are straight line segments. And, in that case, the shape is a quadrilateral.
A closed figure formed by 3+ segments that don't cross is a polygon. One with 3 sides is a triangle, one with 4 is a quadrilateral, one with 5 is a pentagon, one with 6 is a hexagon, etc.
the two adjacent angles formed by the intersecting lines will equal 180 degrees.
ANSWER
A quadrilateral in which adjacent angles are congruent is called a kite. In a kite, the adjacent angles formed by the intersecting diagonals are congruent. This property distinguishes a kite from other types of quadrilaterals, such as a parallelogram or a rhombus, where adjacent angles are not necessarily congruent. Kites have specific properties and characteristics that make them a unique type of quadrilateral in geometry.

No... a quadrilateral is a figure of 4 sides. Trapzoid, square, diamond.... get the picture? A right angle is an angle. It is formed by two lines intersecting. They don't even necessarily make a shape.

A rhombus is formed.

A large compound formed by the joining of smaller compounds is called a polymer.
