💡 Quick Answer & Definition(Verified Formula)
Find hypotenuse (c) or legs (a, b) in right triangles using a² + b² = c².
The Pythagorean Theorem: a² + b² = c²
States that in any right triangle, the square of the hypotenuse (c) equals the sum of the squares of the two adjacent legs (a and b).
Solving for Hypotenuse vs. Missing Leg
To find hypotenuse: c = √(a² + b²). To find a missing leg: a = √(c² − b²).
Practical Construction & Navigation Uses
Carpenters and builders use 3-4-5 right triangle ratios to ensure walls and foundation footings are perfectly square.
