Angle Angle Side

Adjust the angles by sliding, and the length of side "c" by dragging. Then move point "C" until a triangle is formed. Note that because of tolerance issues, you sometimes have to fiddle with the length of side b to make the triangle show up. I'm having a difficult time getting the proper "epsilon."

To solve the triangle, use the "adds to 180" property to find the missing angle. Then, use the invariant (side c)/(sin(C)) to find side a and side b.
