  2. What must we know in order to use the Pythagorean Theorem? Two sides of a right triangle.

  3. This note sheet examines two special right triangles. They are special because we only need to know the length of 1 side to find the length of the other two sides.

  4. 45-45-90 or Isosceles Right TriangleIn a 45-45-90 triangle, the hypotenuse is equal to the length of a leg times____.

  5. Examples: Find the length of x and y.

  6. In a 30-60-90 triangle, the hypotenuse equals two times the shorter leg and the longer leg equals the shorter leg times .

  7. Examples: Find the length of x and y.

  8. Example: Find the perimeter of a square with diagonals of length 25cm.
