Box of Blue Triangles

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:

• 30^o x 12 triangles = 360^o
• 60^o x 6 triangles = 360^o
• 90^o x 4 triangles = 360^o
• 360^o / 30^o = 12 triangles
• 360^o / 60^o = 6 triangles
• 360^o / 90^o = 4 triangles
• 360^o / 12 triangles = 30^o
• 360^o / 6 triangles = 60^o
• 360^o / 4 triangles = 90^o
