The Pythagorean Theorem
⭐ MasteredIn a right-angled triangle, the square of the longest side equals the sum of the squares of the other two sides. This is written as a squared plus b squared equals c squared.
💡 Fun fact
A ladder leaning against a wall forms a right triangle that can be solved with this rule.
All about The Pythagorean Theorem
In a right-angled triangle, the square of the longest side, called the hypotenuse, equals the sum of the squares of the other two sides. This is written as a squared plus b squared equals c squared.
