Student Exploration

Do the angles in a triangle always add up to 180 degrees? How are the lengths of the sides of a triangle are controlled by the sizes of the angles in Spherical Geometry?

Extension Investigation

  1. Students can make a presentation like the one below http://www.youtube.com/watch?v=b7DmUymGR28&feature=related
  2. Virgo is one of the constellations of Zodaic. Three principal stars of the constellation form a triangle. If m \angle S = 25 and m \angle P = 135, then find the m \angle V. http://worksheets.tutorvista.com/angles-in-a-triangle-worksheet.html

Layering (optional)

How do we show that all of the angles the triangle add up to 180?
