Find the missing the coordinates. Tiles (2, 1) (2, -2) (-5, -5) (-1, -1) Pairs A(2, 5), B(6, 5), and C(6, 1) are three vertices of square ABCD. What are the coordinates of vertex D? arrowBoth A(2, 3), B(7, 3), and C(7, -2) are three vertices of square ABCD. What are the coordinates of vertex D? arrowBoth A(-5, -1), B(1, -1), and C(1, -5) are three vertices of rectangle ABCD. What are the coordinates of vertex D? arrowBoth A(-1, 4), B(7, 4), and C(7, -1) are three vertices of rectangle ABCD. What are the coordinates of vertex D

Question
Answer:
1) Pairs A(2, 5), B(6, 5), and C(6, 1)
point D
Dx=Cx-(Bx-Ax)=(6-(6-2))=2
Dy=Cy=1
the coordinates of vertex D is (2,1)

2) Pairs A(2, 3), B(7, 3), and C(7, -2)
point D 
Dx=Cx-(Bx-Ax)=(7-(7-2))=2
Dy=Cy=-2
the coordinates of vertex D is (2,-2)

3) Pairs A(-5, -1), B(1, -1), and C(1, -5)
point D 
Dx=Cx-(Bx-Ax)=(1-(1+5))=-5
Dy=Cy=-5
the coordinates of vertex D is (-5,-5)

4) Pairs A(-1, 4), B(7, 4), and C(7, -1)
point D 
Dx=Cx-(Bx-Ax)=(7-(7+1))=-1
Dy=Cy=-1
the coordinates of vertex D is (-1,-1)
