Page 4: Pythagorean Theorem and Its Applications
This page introduces the Pythagorean theorem and its practical applications in geometry.
Definition: Pythagorean theorem - In a right-angled triangle, the square of the hypotenuse is equal to the sum of squares of the other two sides c2=a2+b2.
Key concepts covered:
- Using the Pythagorean theorem to find missing sides in right-angled triangles.
- Verifying if a triangle is right-angled using the theorem.
- Solving real-world problems using the Pythagorean theorem.
Example: In a right-angled triangle with sides 3cm and 4cm, the hypotenuse is √32+42 = 5cm.
The page includes various practice problems and real-world applications, such as calculating distances in navigation.
Highlight: The Pythagorean theorem is a fundamental concept in trigonometry and has numerous practical applications in fields like construction, navigation, and physics.
