More Than One?

Students consider both the lengths and the angles of triangles. They recognize that two triangles with two angle measures and one side length in common (or two side lengths and one angle measure in common) are not necessarily identical copies. Students also come to understand that knowing the order of the measurements can help create identical triangles.
