Answer:
Quadrilateral A(11, -7), B(9, -4), C(11, -1), and D(13, -4) forms a rhombus.
Quadrilateral A(11, -7), B(9, -4), C'(11,1), and D(13, -4) forms a kite.
Step-by-step explanation:
Rhombus is a quadrilateral whose all sides have equal length.
Kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides which are adjacent to each other.
The quadrilateral formed by the vertices A(11, -7), B(9, -4), C(11, -1), and D(13, -4) would result in a rhombus (see figure below) because it had four equal sides.
If C(11,-1) is shifted to the point C'(11,1), it would become a kite (see figure below) because it has two pairs of equal sides.
