Study Notes

Pythagorean Theorem

Hypotenuse

  • The hypotenuse is the longest side of a right triangle, opposite the right angle (90°)
  • It is the side c in the formula: a² + b² = c²

Right Triangles

  • A right triangle is a triangle with one right angle (90°)
  • The Pythagorean theorem only applies to right triangles

Triangle Geometry

  • The Pythagorean theorem relates the lengths of the sides of a right triangle
  • The theorem states: a² + b² = c², where a and b are the legs and c is the hypotenuse
  • The theorem can be used to find the length of the hypotenuse or either leg

Proofs and Theorems

  • The Pythagorean theorem can be proven using various methods, including:
    • Geometric proof using area of squares
    • Algebraic proof using similarity of triangles
    • Trigonometric proof using sin and cos functions
  • The theorem is a fundamental principle in geometry and trigonometry

Applications in Trigonometry

  • The Pythagorean theorem is used to find the length of sides and angles in right triangles
  • It is essential in trigonometric identities, such as sin²(A) + cos²(A) = 1
  • The theorem has applications in solving triangular problems, including:
    • Finding distances and heights in trigonometry
    • Calculating angles and side lengths in right triangles
