If (1,2),(4,y),(x,6) and (3,5) are the vertices of a parallelogram taken in order, find x and y

Understanding Parallelogram Properties

A parallelogram is a quadrilateral with opposite sides that are parallel to each other. In a parallelogram, the opposite sides are equal in length and the opposite angles are equal in measure. Given the vertices of a parallelogram as (1,2), (4,y), (x,6), and (3,5), we need to find the values of x and y.

Midpoint Formula

To find the values of x and y, we can use the midpoint formula. The midpoint formula states that the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) is given by:

(x1 + x2)/2, (y1 + y2)/2

Since the diagonals of a parallelogram bisect each other, we can use the midpoint formula to find the midpoint of the diagonals.

Midpoint of Diagonal 1

Let's find the midpoint of the diagonal with endpoints (1,2) and (x,6). The midpoint of this diagonal is given by:

(1 + x)/2, (2 + 6)/2

Simplifying the above equation, we get:

(1 + x)/2, 4

Midpoint of Diagonal 2

Now, let's find the midpoint of the diagonal with endpoints (4,y) and (3,5). The midpoint of this diagonal is given by:

(4 + 3)/2, (y + 5)/2

Simplifying the above equation, we get:

7/2, (y + 5)/2

Equating Midpoints

Since the diagonals of a parallelogram bisect each other, the midpoints of the diagonals are equal. Equating the midpoints of the two diagonals, we get:

(1 + x)/2 = 7/2

(2 + 6)/2 = (y + 5)/2

Simplifying the above equations, we get:

1 + x = 7

8 = y + 5

Solving for x and y

Now, let's solve the above equations to find the values of x and y.

1 + x = 7

x = 6

8 = y + 5

y = 3

Conclusion

Therefore, the values of x and y are 6 and 3, respectively.
