Answer:
(8,9)
Step-by-step explanation:
Given
[tex]A = (2,6)[/tex]
[tex]B = (2,9)[/tex]
[tex]C = (8,6)[/tex]
Required
Determine the 4th point
The coordinate point of a horizontal or a vertical rectangle is given as:
(x1,y1), (x2,y2), (x3,y3), (x4,y4)
Where:
[tex]x_1 = x_2[/tex] [tex]x_3 = x_4[/tex] [tex]y_1 = y_3[/tex] [tex]y_2 = y_4[/tex]
So, we have:
[tex]A = (2,6)[/tex] --- [tex](x_1.y_1)[/tex]
[tex]B = (2,9)[/tex] ---- [tex](x_2.y_2)[/tex]
[tex]C = (8,6)[/tex] ---- [tex](x_3,y_3)[/tex]
Using the above equations:
[tex]x_3 = x_4[/tex][tex]=8[/tex]
[tex]y_2 = y_4[/tex] [tex]= 9[/tex]
Hence, the coordinate of the 4th point is:
[tex](x_4,y_4) = (8,9)[/tex]
