The 3, 4, 5 Triangle

Mar 3, 2020 | Hinsdale

Today's math fact comes from Wolfram MathWorld!

The triangle with edge lengths 3, 4, and 5 is the right triangle with smallest possible integer lengths and corresponds to the Pythagorean triple (3,4,5) where the legs have lengths 3 and 4 and the hypotenuse length 5. It satisfies the Pythagorean theorem since

The formula for the area of a triangle is 1/2 x base x height

The formula for finding the hypotenuse is a² + b² = c²
