The correct equation for finding the number of sides for an equiangular polygon is: 180=(n-2) Shall demonstrate a sample problem if needed.
There are a number of different, and sometimes overlapping, classifications. Polygons may be convex or concave. In a convex polygon, any two points inside the polygon are joined by a straight line that is wholly inside the polygon. In a concave polygon there are at least two points such that the line joining them intersects its boundary. Polygons can by equilateral (all sides of equal length), or equiangular (all angles of equal measure) or regular (all sides equal AND all angles equal). Note that in general (unlike for triangles) equilateral and equiangular are not the same. Polygons can be classified according to the number of sides/angles.
Also doubled.
Neither. The orthocentre is one point. A point does not have a number of sides that can be equal (equilateral) nor can it have a number of angles that can be equal (equiangular).
The exterior angles get smaller
If the volume is doubled and the number of molecules is doubled while the temperature is held constant, the pressure of the gas sample will remain the same. This is because both the volume and the number of molecules increased by the same factor, resulting in no net change in pressure according to the ideal gas law.
Each external angle is equal to 360/n degrees where n is the number of sides (or angles) of the polygon. So the external angle is inversely proportional to the number of sides.
The volume is doubled.
2+2=4 because 2 is a number doubled from 1 wich means 2 +2=4 not 4
it will decrease
Assuming that the phrase "doubled by 2" is tautological, the expression for a number multiplied by 2 (or a number doubled) is 2n.
If the number is doubles its total is doubled since its total is itself!
