This should show the students the part of the ambiguous case where no triangles are formed. I simply edited the applet by galvinj by making <B=60 degrees as opposed to 30 degrees used to show the two triangles case. To edit angles as I did, you need to (less)

This learning video deals with a question of geometrical probability. A key idea presented is the fact that a linear equation in three dimensions produces a plane. The video focuses on random triangles that are defined by their three respective angles. These angles are chosen randomly subject to a constraint that they must sum to 180 degrees. An example of the types of in-class activities for between segments of the video is: Ask six students for numbers and make those numbers the coordinates x,y of three points. Then have the class try to figure out how to decide if the triangle with those corners is acute or obtuse. (less)
