Answer:
The correct answer option is B. (5, 8).
Step-by-step explanation:
We are given the following coordinates of the vertices of a square and we are to find the coordinates of its fourth vertex:
[tex] ( - 1 , 2 ) , ( - 1 , 8 ) , ( 5 , 2 ) [/tex]
We know that all four sides of the square are equal so the vertices are equidistant from each other.
So the fourth vertex will be (5, 8).
