The diagonals of a parallelogram are congruent. which could be the parallelogram?

Rectangle

Step-by-step explanation:

Let's see definitions of parallelogram, trapezoid, rectangle, kite and rhombus.

Parallelogram is a quadrilateral with two pairs of parallel opposite sides and opposite sides are equal.

Trapezoid is a quadrilateral with one pair parallel opposite sides, trapezoid is not parallelogram.

Rectangle is a parallelogram with all angles right. Rectangle has diagonals that are congruent.

Kite is a quadrilateral with two pairs of congruent adjacent sides. Kite is not parallelogram.

Rhombus is a parallelogram with all sides congruent. The diagonals of the rhombus are not congruent, but they are perpendicular bisectors of each other.

Therefore, answer is Rectangle.

Hope this will help you.

Thank you.

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
