So the definition of a regular polygon is that the sides are all equal, the interior angles are all equal, and the exterior angles are all equal.
Notice how with #s 3 and 4, the angles are all shown as equal, as well as their sides. However, #s 5 and 6 have different angles and sides, respectively.
Therefore 3 and 4 are regular, but 5 and 6 are irregular (not regular).

Find two consecutive numbers whose sum is 115
melamori03 [73]
Let the first consecutive number be n then,

n + (n+1) = 115, since they are consecutive, n+1 is the next number.
2n+1=115 \Rightarrow 2n = 114 \Rightarrow n=57

Hence the two consecutive numbers that sum to 115 are 57 and 58.
