At its heart, Pythagoras' Theorem describes the relationship between the sides of a right-angled triangle. A right-angled triangle, remember, has one angle that's exactly 90 degrees (a right angle). The longest side, opposite the right angle, is called the hypotenuse (often labeled as 'c'). The other two sides are called the legs (often labeled as 'a' and 'b').
The theorem states: a² + b² = c²
In plain English: The square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
Fun Fact: Pythagoras wasn't actually the first to discover this relationship! Evidence suggests that the Babylonians and Egyptians knew about it long before him. However, Pythagoras and his followers are credited with providing the first proof of the theorem.
Okay, let's get practical. How do we actually use this theorem to solve problems? Here are a few examples, similar to what you might find in your Singapore Secondary 3 math textbook:
Finding the Hypotenuse: Imagine a right-angled triangle where one leg is 3 cm and the other is 4 cm. What's the length of the hypotenuse?
Finding a Leg: Suppose you know the hypotenuse is 13 cm and one leg is 5 cm. What's the length of the other leg?
Key takeaway: Always identify the right angle and the hypotenuse first before plugging in the values into the formula. Don't blur sotong and mix them up!
Pythagoras' Theorem isn't just confined to textbooks; it's all around us!
Interesting Fact: The Great Pyramid of Giza, built thousands of years ago, incorporates Pythagorean ratios in its dimensions, suggesting that ancient Egyptians were familiar with the principles of the theorem.
Pythagoras' Theorem is a cornerstone of geometry and trigonometry. Understanding it opens the door to more complex concepts, such as trigonometric ratios (sine, cosine, tangent) and angle relationships.
