In Nebraska, servers need to be at least 19 years of age in order to sell and serve alcohol, but only 16 to handle and dispose of alcohol containers. This means a 19-year-old can bartend and a 16 year-old-can haul full and empty liquors bottles to and from a Nebraska bar.
A triangle with one interior angle measuring more than 90Â° is an obtuse triangle or obtuse-angled triangle. If c is the length of the longest side, then a2 + b2 < c2, where a and b are the lengths of the other sides. A triangle with an interior angle of 180Â° (and collinear vertices) is degenerate.
Scalene. Another type of triangle which can be either isosceles or scalene is a right triangle. A right triangle is a triangle where one of the angles is 90Âº. A right triangle cannot be an equilateral triangle because all of the angles in an equilateral triangle are 60Âº. There are also two other designations of triangles, acute and obtuse. Acute triangles are triangles where all three angles are less than 90Âº.
