Determine if the given side lengths could be used to form a unique triangle, many different triangles, or no triangles.

20.2 in., 11 in., 8.2 in.

A.
unique triangle

B.
many different triangles

C.
no triangles

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
