The
most important theorem in mathematics is the “Pythagoras Theorem” also known as
“Pythagorean Theorem”. It is used to define the relation between three sides of
a triangle. Pythagoras Theorem is stated as the square of the length of the
hypotenuse side of a right triangle is equal to the sum of the square of the
length of the other two sides. From the theorem, the Pythagorean equation that
relates the length of the sides of a triangle a, b, and c is given as
c2
= a2 + b2
From
the properties of triangles,
the Pythagorean theorem is derived from the right-angled triangle, where one of
the internal angles of a triangle is 90 degrees. Other two angles of a triangle
may be of equal degrees or it may vary. From the triangular property, it should
satisfy the condition that the sum of the interior angles of a triangle is
equal to 180 degrees. If the angles of a triangle are 45-90-45 degrees, it is
called an isosceles right triangle where the value of the two angles remains
the same.
If the angles become 30-90-60 degrees, then it is called right
scalene triangle. All the angles are different in the right scalene triangle.
If the two sides of a right triangle are of unit length, then the diagonal
value of the triangle is equal to the square root of 2 and it is
called “Pythagoras’ constant”. The value of Pythagoras constant is
approximately equal to 1.414. Some of the real-time applications of Pythagorean
theorem are:
● To
determine the slope of a triangle
● Used
in architecture and construction field.
● Used
in navigation to find the shortest distance.
● To
create maps, the Pythagorean theorem is used before, to calculate the numerical
distance.
● Pythagoras
theorem is applied to any equation that contains square values.
● In
computer science, it is used in bubble sort algorithm to increase the
processing time which takes the square of the input value time to run.
● It
is used in the trigonometric function to find the angles of a right triangle.
