Geometría
Geometry is the study of all the parameters and characteristics that a polygon has, knowing that a polygon is a figure that is formed by the union of lines in 2 dimensions, such as the square, the rectangle, the triangle, and figures that do notThey are considered of the main ones, here they also enter figures that are made at random without following any pattern.
The geometry also enters other types of figures such as the circle, the circle cannot be considered a polygon because only the figures that are formed by straight lines are considered polygons, and the circle is a figure that forms a curved line, butIt is also studied in geometry.
Geometry study
To mention some characteristics that are studied in geometry (and by "study" it is understood that it is "how to find this part") are the sides of the geometric figures (in case of the circle the circumference), the area, the perimeter, I enterother parts.
