Pythagoras Theorem: This article explains the concept of Pythagoras Theorem and its converse. Know the definition, formula, proof, examples and applications of Pythagoras Theorem.

The Pythagorean theorem provides an equation to calculate the longer side of a right triangle by summing the squares of the other two sides. It is often phrased as a2 + b2 = c2.

The two women and St. Mary’s Academy graduates who used trigonometry to prove the 2000-year-old Pythagorean Theorem math equation, had their findings confirmed.
