📚 What is the Pythagorean Theorem?

The Pythagorean Theorem is one of the most important concepts in geometry. Named after the ancient Greek mathematician Pythagoras, the theorem applies to right-angled triangles.

The formula is:

rCopyEdita² + b² = c²

Where:

a and b are the two shorter sides (legs)
c is the hypotenuse (the side opposite the right angle)

Example:
If a = 3 and b = 4, then:

rubyCopyEdit3² + 4² = 9 + 16 = 25  
=> c = √25 = 5

⚙️ How a Pythagorean Calculator Works

A Pythagorean calculator automates this formula. You input any two values, and it calculates the third. It removes the need for manual computation and ensures precise results instantly.

🔄 Types of Input Options:

Find Hypotenuse (c)
Input: a and b
Output: c
Find One Leg (a or b)
Input: c and one leg
Output: missing leg
Reverse Calculation
Verify whether given sides satisfy the theorem

🧠 Pythagorean Theorem Explained with Real-World Examples

🧱 Construction:

A construction worker wants to ensure the wall is perpendicular. If one side is 6 feet and the other is 8 feet, then:

makefileCopyEdit6² + 8² = 36 + 64 = 100  
c = √100 = 10 feet

So if the diagonal (hypotenuse) is 10 feet, the wall is correctly aligned.

🧭 Navigation:

A hiker moves 3 miles north and 4 miles east. What’s the shortest distance back?

rubyCopyEdit3² + 4² = 9 + 16 = 25  
=> c = √25 = 5 miles

He is 5 miles from the starting point.
