This lesson shows a visual proof of the Pythagorean Theorem (\(a^2 + b^2 = c^2\)) – one of the most famous formulas in geometry.

Most students know the formula, but do you know why it works? In this lesson, we break it down with a simple, visual explanation.

❖ The Pythagorean Theorem applies to any right-angled triangle and states that:

The square of the hypotenuse is equal to the sum of the squares of the other two sides.

For example, if triangle \(ABC\) has a right angle at \(B\), then:

\((AB)^2 + (BC)^2 = (AC)^2\)

where \(AC\) is the hypotenuse (the longest side opposite the right angle).

❖ The hypotenuse is always the longest side and lies opposite the \(90°\) angle.

✅ This lesson is perfect for students and learners looking for a clear, easy-to-follow proof. Whether you’re preparing for a test or reviewing geometry basics, this explanation makes the concept simple and visual.
