The sides of triangles do not have set names, except in the case of the right triangle (where one side opposite the right angle is called the hypotenuse). They are usually labâ¦elled arbitrarily a, b and c.
Mound Builders lived in the Ohio River Valley and in the Wisconsin area. Also, Mound Builders lived from the Great Lakes to the Gulf of Mexico and from the Mississippi and Missouri Rivers to the Appalachian mountains.
Conical mounds were sometimes also used as cemeteries for important families, although only a small number of Caddo were actually buried in mounds. Few people resided at Caddo mound centers. Most lived in family homesteads and small villages scattered across the countryside and congregated at the centers only for important events.
