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.
Types of Triangle by Angle. In an equiangular triangle, all the angles are equalâeach one measures 60 degrees. An equiangular triangle is a kind of acute triangle, and is always equilateral. In a right triangle, one of the angles is a right angleâan angle of 90 degrees. A right triangle may be isosceles or scalene. In an obtuse triangle, one angle is greater than a right angleâit is more than 90 degrees. An obtuse triangle may be isosceles or scalene.
