Aquadrilateral has vertices a(11, -7), b(9, -4), c(11, -1), and d(13, -4).
quadrilateral abcd is a
-parallelogram with non-perpendicular and non congruent adjacent sides
-trapezoid with exactly one pair of parallel sides
-rectangle with non congruent adjacent side
-rhombus with perpendicular
if the vertex c(11, -1) were shifted to the point c′(11, 1), quadrilateral abc′d would be a
-paralellogram with non-perpendicular adjacent sides
-kite
-square
-rhombus with non perpendicular adjacent sides

1) rhombus with nonperpendicular adjacent sides. Because all the sides are congruent and non of the angles are right angle.

2)Kite. A pair of sides are equal, and the other pair are equal.
