The coordinate matrix that describes the quadrilateral ABDC is
Ax Ay 5 6
Bx By -1 4
Cx Cy = 5 3
Dx Dy -1 1
What is coordinate matrix?
The coordinate matrix represents the vertices of the quadrilateral ABCD in a matrix form. Each row corresponds to a vertex, and the columns represent the x and y coordinates.
For the given vertices A(5,6), B(-1,4), C(5,3), and D(-1,1), the coordinate matrix is:
Ax Ay 5 6
Bx By -1 4
Cx Cy = 5 3
Dx Dy -1 1
So, the first row [5, 6] represents the coordinates of point A, the second row [-1, 4] represents point B, third row [5,3] represents point C and fourth row [-1,1] represents point D Each column corresponds to the x and y coordinates, respectively.
