(a)
To graph: The parallelogram with the vertices
(a)

Explanation of Solution
Given information:
The vertices of the parallelogram
Graph:
The parallelogram with vertices
Interpretation:
A parallelogram is a convex
A parallelogram is a quadrilateral whose diagonals bisect each other at the same point.
Opposite angles of a parallelogram are equal i.e.
The given vertices of the parallelogram satisfy all the conditions in the plotted figure.
(b)
To calculate: The mid-points of the diagonal of the parallelogram ABCD.
(b)

Answer to Problem 47E
The coordinates of mid-point of parallelogram ABCD is
Explanation of Solution
Given information:
The vertices of the parallelogram
Formula used:
Mid-point formula between two points
Calculation:
Consider the provided vertices of the parallelogram
By plotting the given points on the coordinate plane, we get the following figure,
Recall that the mid-point formula between two points
So, midpoint of AC is calculated as,
Now, midpoint of BD is calculated as,
Thus, the coordinates of mid-point of parallelogram ABCD is
(c)
To verify: The diagonals of the parallelogram bisects each other.
(c)

Explanation of Solution
Given information:
The vertices of the parallelogram
Formula used:
If two diagonals are intersected by each other at the same point then the diagonals bisect each other at that point.
Proof:
Consider the given vertices of the parallelogram ABCD
From part (b), it is observed that the midpoint of the diagonals of the parallelogram coincide each other.
Recall if two diagonals are intersected by each other at the same point then the diagonals bisect each other at that point.
Thus, it is proved that the diagonals of the parallelogram ABCD bisects each other at the point
