Pentagons have 5 sides and they can be regular or irregular
Any regular shapes have equal sides, including squares and equilateral triangles. Irregular shapes can also have equal sides, but not equal angles.
To find the area, first divide the shape into regular, simple shapes. Then use formulas to find the area of the smaller, regular shapes. Lastly, add up all the smaller areas to find the area of the original shape.
Shapes tessellate to fit around an interior angle. They also tessellate because they are regular polygons; non-regular polygons cannot tessellate. * * * * * Not correct. All triangles and quadrilaterals will tessellate, whether regular or irregular. Contrary to the above answer, a regular pentagon will not tessellate but there are 14 different irregular pentagons which will tessellate (the last was discovered in 2015). Three convex hexagons will do so as well. No polygon of 7 or more sides will tessellate - whether they are regular (contrary to the above answer) or irregular.

Regular shapes are both equilateral and equiangular. Irregular shapes may or may not be equilateral and equiangular.
Regular shapes:all sides and angles are the same Irregular shapes: different angle and sides
Regular shapes have equal sides and angles, like squares and equilateral triangles. Irregular shapes have sides and angles of varying lengths and measurements, like rectangles and scalene triangles. Regular shapes are typically easier to calculate and work with compared to irregular shapes.
Irregular shapes are made up of regular ones; add them together.
To find the area of irregular shapes, first, we need to divide the irregular shape into regular shapes that you can recognize such as triangles, rectangles, circles, squares and so forth. Then, find the area of these individual shapes and add them to get an area of irregular shap
If you mean 'Irregular' and 'Regular shapes' then this is the answer. A regular shape is a shape that has E.g. 4 sides that are the same length but and irregular shape is one that has the same amount of sides, just different lengths.
Each body has its own centre of gravity. The centre of gravity of two regular shapes - an equilateral triangle and a square will be different so why should the cog of a regular and an irregular shape not be different?

Irregular shapes are all around. Most shapes are irregular.
an circle and shapes that are not regular dumhead
A regular polygon has all its angles and equal and all its sides equal. Irregular poygons do not. Some people consider only convex shapes meeting these criteria as being regular polygons while others include "star" shapes.
