Quadrilateral ABCD have vertices at A (-4,4), B(1, 1,), C(4,6), and D (-1,9). Based on the properties of the diagonals, I’d quadrilateral ABCD a rectangle, rhombus, or square? Use the distance and slope formulas to prove your conclusion.

Quadrilateral ABCD with vertices at A (-4,4), B(1, 1,), C(4,6), and D (-1,9). a rhombus.
A quadrilateral is a polygon with four sides and four angles. A rhombus is a quadrilateral in which opposite sides are equal and parallel. All the sides of a rhombus are congruent to each other, and opposite angles are congruent.
From the plot of Quadrilateral ABCD, we can see that all sides are equal. Quadrilateral ABCD with vertices at A (-4,4), B(1, 1,), C(4,6), and D (-1,9). a rhombus.
