Pythagorean Theorem

The Pythagorean Theorem is a geometrical expression used often in math and
physics. It used to 2 2 2 find the unknown side of a right triangle. The
exponential form of this theorem a + b = c . That is the equation you use when
you are looking for the unknown side of a right triangle, and it is what Ill
demonstrate on the attached exhibit. The upside down capital L in the bottom of
the left hand corner indicates that sides A & B are the legs of the
triangle. Since we know side A = 5 inches and B = 3 inches we may fill that in
to 2 2 2 or equation for step one. (1) 5 + 3 = c What the theorem will help us
find is the c side of this triangle. 2. 25 + 9 = c All we do is distribute 5 to
the second power and 3 to the second power as seen is step two. Next, we add
these two numbers together to get 34, 25+9=34, in step three. 3. 25+9=34 Then,
in step four we find the square root of 34. 4. 34 In step five we see that 5.83
is the unknown side of the right triangle. 5. c= 5.83 We found this answer by
using the Pythagorean Theorem as taught in geometrical form. This theorem may
also be summed up by saying that the area of the square on the hypotenuse, or
opposite side of the right angle, of a right triangle is equal to sum of the
areas of the squared on the legs. The Pythagorean Theorem was a studied by many
people and groups. One of those people being Euclid. Sometimes the Pythagorean
Theorem is also referred to as the 47th Problem of Euclid. It is called this
because it is included by Euclid in a book of numbered geometric problems. In
the problem Euclid studied he would always use 3, 4, and 5 as the sides of the
right triangle. He did this because 5 x 5 = 3 x 3 + 4 x 4. The angle opposite
the side of the legs was the right angle, it had a length of 5. The 3:4:5 in the
right triangle was known as a Pythagorean triple or a three digits that could be
put in a right triangle successfully. These three numbers were also whole
numbers and were used in the Egyptian string trick, which I will talk about
later. This Pythagorean triple, 3:4:5, are the smallest integer series to have
been formed, and the only consecutive numbers in that group that is important.
These numbers can be, and often were, studied from a philosophical stand point.
The symbolic meanings of the 3:4:5 triple told by modern writers such as Manly
P. Hall say 3 stands for spirit, 4 stands for matter, and 5 stands for man.
Using Halls study the symbolism of this arrangement is as follows:
Matter (4) lays upon the plane of Earth and Spirit (3) reaches up to
the Heaven and they are connected by Man (5) who takes in both qualities.
A process similar to that of Euclid's 47th Problem was the Egyptian string
trick. Egyptians were said to have invented the word geometry (geo = earth,
metry = measuring.) The Egyptians used the 3:4:5 right triangle to create right
triangles when measuring there fields after the Nile floods washed out there old
boundary markers. The Egyptians used the same theory of Euclid, 5 x 5 = 3 x 3 +
4 x 4, to get there boundaries marked correctly. Although Euclid and the Ancient
Egyptians studied the theorem, the true inventor of it ( or the person most
people believed invented it first ) was Pythagoras of Samos and his group the
Pythagoreans. Pythagoras was a man born in 580 B.C. on the island of Samos, in
the Aegean Sea. It is said Pythagoras was a man that spent his life traveling
the world in search of wisdom. This search for wisdom led him to settle in
Corona, a Greek colony in southern Italy, in about 530 B.C. Here Pythagoras
gained famous status for his group known as the Brotherhood of Pythagoreans.
This group devoted there lives to the study of mathematics. The group, as led by
Pythagoras, could be described as almost cult-like because that it had symbols,
rituals, and prayers. The group was also cult-like because of there odd ways of
not writing down any
