Pythagorean Theorem

What is the Pythagorean Theorem and Who discovered it ?

In a right angled triangle of 90 degrees, the square of the hypotenuse (C) is equal to the sum of the squares of the opposite (B) and the adjacent (A). The hypotenuse is the longest side of a right-angled triangle. The equation is : A squared + B squared = C squared.

How to decipher the Egyptian Hieroglyphic writing ?

Egyptian hieroglyphic is the first writing ever used, along with Sumerian, which is now southern Iraq. The word hieroglyph comes from the Greek hieros (sacred), and glypho (inscriptions). The Egyptian writing was created in 3,400 BC.

Ancient Egyptians had more than 2,000 characters called hieroglyphics. Each hieroglyphic is a common object that represents a letter of their alphabet.

Hieroglyphics were written in rows or columns without spaces. And can be read from left to right or from right to left. The symbols (human and animals) always face towards the beginning of the line so you know which direction to start reading.
