The student will be able to solve triangles using the Law of Sines and identify when the situation calls for the Law of Sines.

- To change the size of angle
*A*, move point*C*. - To change the size of segment
*a*move point.*B* - Move point
*B*so that a triangle is formed. - What is the relationship between
*a*,*b*and*h*when a triangle is not formed? - What is the relationship between
*a*,*b*and*h*when a triangle is formed?

- Keeping the measures of
*a*,*b*and*h*constant, can more than one triangle be formed? - What is the relationship between
*a*,*b*and*h*? - Do the relationships remain the same when ∠
*A*is obtuse?
