Pythagoras' Theorem and Applications

🎬 Video Tutorial

  • Pythagoras’ Theorem: In a right-angled triangle, the square of the hypotenuse equals the sum of the squares of the other two sides ($a^2 + b^2 = c^2$).
  • Finding the Missing Side of a Triangle: Substitute known side lengths into the equation to solve for the unknown side.
  • Coordinate Geometry Application: Determine the distance between two points by using horizontal and vertical distances to form a right triangle.
  • 3D Pythagoras: Use to find diagonals in cuboids, which is useful for calculating distances in three-dimensional shapes.
