  • Twelve blue right-angled scalene triangles with no black lines.
  • The angles measure 30, 60, and 90 degrees.


Use of the triangle as a constructor to indirectly demonstrate the following:
30o x 12 triangles = 360o
60o x 6 triangles = 360o
90o x 4 triangles = 360o
360o / 30o = 12 triangles
360o / 60o = 6 triangles
360o / 90o = 4 triangles
360o / 12 triangles = 30o
360o / 6 triangles = 60o
360o / 4 triangles = 90o
