In a right triangle, the sum of the squares of the lengths of the legs, is equal to the square of the length of the hypotenuse.
This statement refers to the Pythagorean Theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides, known as the legs
This statement refers to the Pythagorean Theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides, known as the legs.
Mathematically, if we have a right triangle with legs of lengths a and b, and a hypotenuse of length c, then the Pythagorean Theorem can be expressed as:
a^2 + b^2 = c^2
Let’s understand this theorem with an example:
Consider a right triangle with one leg measuring 3 units and the other leg measuring 4 units. To find the length of the hypotenuse, we can use the Pythagorean Theorem.
a = 3
b = 4
c^2 = a^2 + b^2
Substituting the given values into the equation, we get:
c^2 = 3^2 + 4^2
c^2 = 9 + 16
c^2 = 25
Now, to find the length of the hypotenuse (c), we take the square root of both sides:
c = √25
c = 5
Therefore, in this right triangle, the hypotenuse has a length of 5 units, and the Pythagorean Theorem holds true:
3^2 + 4^2 = 5^2
9 + 16 = 25
The sum of the squares of the lengths of the legs (9 + 16) is indeed equal to the square of the length of the hypotenuse (25).
The Pythagorean Theorem is a fundamental concept in geometry, and it enables us to solve various problems involving right triangles, such as finding missing side lengths, determining whether a triangle is a right triangle, and more.
