If the figure is irregular, you can't calculate its area (for example) with some simple formula. You need to use integration - which basically means to divide the figure into many narrow strips, which you assume to be rectangles.

A sphere, an ellipsoid, a torus (donut), an irregular blob with no pointy bit.
An octagon can be either regular or irregular. A regular octagon in a 2-dimensional closed figure with eight sides, all of which are the same length. This means that all the angles are the same, too. An irregular octagon is a 2-dimensional closed figure with eight sides, but at least two of the sides are of different length. All sides can be of different lengths.
A four sided figure with no parallel sides is a trapezium, but it is also an irregular four-sided polygon, tetragon, quadrilateral, or quadrangle.
It depends on the irregular figure. A rectangle, for example, has two.
an irregular figure is when it is open or have curved lines.
An irregular hexagon.
method usede to figure the volume of an irregular shaped object
Divide the irregular figure into manageable pieces and work out their individual areas, sum the areas to that of the original figure. Measure the perimeter.
A regular figure has no curves, no gaps, and ALL lines must be connected. An irregular figure is the opposite of that.
A irregular is a closed plane figure formed by three or more line segments.
when its a irregular shape you divide it up
yes as long as it is a closed figure.
heptagon.
A regular or irregular pentagon
An irregular polygon need not be equiangular.
