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.
A triangle can be classified according to its sides, angles, or a combination of both. If a triangle. has three congruent sides, it is called an equilateral triangle as shown below. A triangle with at least two sides congruent is called an isosceles triangle as shown below.
