Consider the following two triangles.
Length is congruent to and length is congruent to . Given that is greater than , what does the hinge theorem tell us about the lengths and ?
Given that , use the hinge theorem to find the range of all possible values of in the figure.
Consider triangles and in the figure.
Without completing any calculations, use the hinge theorem to determine whether is greater than, less than, or equal to .
