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.
The three internal angles of a triangle always add to 180 degrees. An equilateral triangle has three sides of equal length and three equal angles. An isosceles triangle has two sides of equal length and two equal angles. A scalene triangle has no sides of equal length and no equal angles. A right angle triangle has one angle that is 90 degrees. An obtuse triangle has one angle larger than 90 degrees. An acute triangle has angles that are all less than 90 degrees.
