For x-coordinate:6+Dx/2=66+Dx=12Dx=6

Explanation

We are given three vertices of a square ABCD:

$A (2, 3)$

$B (6, 7)$

$C (10, 1)$

We need to find $D (x, y)$ .

Step 1: Understanding the Square Properties
A square has equal sides and perpendicular diagonals. The diagonals also bisect each other at their midpoint.
Step 2: Find the Midpoint of Diagonal AC
The midpoint formula for two points (

1

,

y

1

)

and (

2

,

y

2

)

is:

M = (x _{1} + x _{2/2}, y _{1} + y _{2/2})

For diagonal AC:

M = (2 + 10, 3 + 1/2)

M = (12/2, 4) = (6, 2)

Step 3: Use Midpoint to Find D
Since diagonals bisect each other, midpoint M is also the midpoint of diagonal BD.
Using the midpoint formula for BD:

M = (B _{x} + D _{x} \frac{B _{y} + D _{y/2}}{2,})

Substituting B

6

,

7

)

and M

6

,

2

)

$(6, 2) = (6 + D _{x}, 7 + D _{y})$

Step 4: Solve for D

Equating the coordinates:

For x-coordinate:
$6 + D _{x/2} = 6$ $6 + D_{x} = 12$ $D_{x} = 6$
For y-coordinate:
$7 + D _{y} = 2$ $7 + D_{y} = 4$ $D_y = -3$

$D = (6, - 3)$

Correct option: (6, -3)
