B.In a right triangle, the hypotenuse equals the sum of the squares of the legs.
C.In a right triangle, the hypotenuse equals the sum of the legs.
D.In a right triangle, the square of the hypotenuse equals the sum of the legs.
The correct answer is A.
The Pythagorean theorem in mathematics is a fundamental relation in geometry referring to the three sides in a right triangle.
The theorem states that the square of the hypotenuse (the side opposite the right angle), is equal to the sum of the squares of the other two sides.
The equation, called the Pythagorean equation, is written as a2+ b2=c2.
The theorem is named after the Greek mathematician Pythagoras.
This theory is one that had been absolutely proved and used in many different fields of studies outside mathematics.
Independent city-states developed in ancient Greece due to some of the city-states being isolated because they were islands (A), and the mountains separating groups of people from one another (C).
Greece's geography played a crucial role in the emergence of independent city-states. The presence of numerous islands (A) and the rugged mountainous terrain (C) fragmented communities, leading to the development of self-sustaining city-states. Isolation on islands or in mountainous regions allowed these city-states to develop distinct cultures, political systems, and economies.
The natural barriers acted as a form of protection against external threats and invasion, contributing to their independence and autonomy. The lack of extensive navigable rivers (D) in Greece diminished their significance for travel and communication compared to the influence of islands and mountains. Thus, the combination of isolation and geographical barriers was instrumental in shaping the independent city-states of ancient Greece.

The picture depicts here a man who is operating a telephone device hence Alexander Graham Bell was invented the First Telephone in 1876. Option D is correct.
An instrument or an electronic device that play a role of medium of communication between a sender and a receiver by converting analog audio voice into electrical signals that can be transmitted while users located over the long distance.
This device enables users to send and receive data with other users across the world and being invented by Alexander Graham Bell in 1876.
This device involves hearing function of ears and vocal function of mouth organ where user can share, talk and send useful information in a shorter period of time.
Therefore, the picture given here clearly defines a person who is speaking by use of the telephone device and it was invented by Graham Bell.
