- A(7, 7)
- B(1, 7)
- C(7, 1)
- D(4, 4)
Step-by-Step Solution
The centre is the midpoint of the diagonal. Opposite vertex = (2*4 - 1, 2*4 - 1) = (8 - 1, 8 - 1) = (7, 7).
Answer: A) (7, 7)
On a grid, a square has its centre at (4, 4) and its sides parallel to the axes. One vertex of the square is at (1, 1).
Find the half-diagonal distances: the vertex is 3 left and 3 down from the centre.
What are the coordinates of the opposite vertex?
