Frequently Asked Questions

Pythagoras theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This is often written as a² + b² = c², where c represents the length of the hypotenuse and a and b represent the lengths of the other two sides.
One helpful mnemonic to remember the order of the terms in Pythagoras theorem is All Students Take Calculus, where A stands for a², S for + (sum), T for b², and C for c².
The Pythagorean theorem is a mathematical principle that applies to all right-angled triangles, while a Pythagorean triple is a specific set of three integers that satisfy the Pythagorean theorem, i.e., a² + b² = c², where c is the largest integer.
To verify your solution, you can always check if the sum of the squares of the two smaller sides equals the square of the largest side. If this equation holds true, then your answer is correct. For example, if you find that the hypotenuse of a right-angled triangle is 5 units, you can check if 3² + 4² = 5² (9 + 16 = 25), which indeed equals 25.
