Hijk is a parallelogram because the midpoint of both diagonals is which means the diagonals bisect each other.

HIJK is a parallelogram because the midpoint of both diagonals is unique and intersect each other, which means the diagonals bisect each other.

Step-by-step explanation:

We are given the following in the question.

HIJK is a parallelogram.

So it satisfies the property of parallelogram.

Thus,

HIJK is a parallelogram because the midpoint of both diagonals is unique and intersect, which means the diagonals bisect each other.

HIJK is the parallelogram

The mid point of both the diagonals is unique and divides both parts of same  diagonal in equal ratios , which means the diagonals bisect each other.

A parallelogram is a quadrilateral with opposite sides equal and parallel to each other. The adjacent angles of parallelogram are not equal to 90° rather they have one pair of equal and opposite acute angles and one pair of equal and opposite obtuse angles.

The figure is attached

From the figure we can write

OH = OJ

OK = OI

According to the property of parallelogram the diagonals of a parallelogram bisect each other.

So we can see that  for a parallelogram HIJK

The mid point of both the diagonals is unique and divides both parts of same  diagonal in equal ratios , which means the diagonals bisect each other.

step-by-step explanation:

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
