Explanation:
Pythagorean Theorem
The
Pythagorean Theorem: The sum of the areas of the two squares on the legs (a and b) equals the area of the
square on the hypotenuse (c).
In mathematics, the Pythagorean Theorem or Pythagoras'
theorem is a relation in Euclidean geometry among the three sides of a right triangle (right-angled triangle). In
terms of areas, it states:
In any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is
equal to the sum of the areas of the squares whose sides are the two legs (the
two sides that meet at a right
angle).
The theorem can be written as an equation relating the lengths of the sides a, b and c,
often called the Pythagorean
equation:
where c represents the length of the hypotenuse,
and a and b represent the lengths of the other two
sides. (Our
solved example in mathguru.com uses this concept)
The Pythagorean Theorem has attracted interest outside mathematics
as a symbol of mathematical abstruseness, mystique, or intellectual power;
popular references in literature, plays, musicals, songs, stamps and cartoons
abound.
