The geometry is a discipline mathematics that originated in ancient Egypt. When the Nile flooded neighboring lands, they were subject to some sort of measurement for proper land distribution. In fact, the word geometry means measuring the earth. Geometric Figures
Geometry is the extension of bodies
When the extension covers two dimensions we are talking about the surface and if we consider three of its dimensions (length, latitude and depth) we are referring to the volume.
A geometric figure is the representation of one or more lines, surfaces or volumes. On the other hand, geometric figures can be of four types: equal, similar, equivalent and symmetric. They are equal when placed overlapping if they coincide. They are similar when they have an equal figure, but different in extension. They are equivalent when they have a different figure and an equal extent. Finally, they are symmetric when their parts are respectively equal, but placed in an inverse way.
Flat geometric figures can be divided according to line type
Those with curved lines are conic figures (the ellipse and the circle , for example). Those with straight lines are polygons. In turn, polygons can be differentiated based on the measurement of their sides and angles (there are regular, irregular, equilateral and equiangle polygons). Polygons can also be classified as internal angles or as a function of their axis of symmetry. However, the most common classification describes the polygons based on the number of sides, the best known figures being: triangle, quadrilateral, pentagon, hexagon , heptagon and octagon.
In the study of geometric figures it is very useful to know their area, that is, the space that lies within the limits of the figure (for example, the area of the triangle would be the result of multiplying its base by the height and dividing the result by two) .
In addition to the area, students need to become familiar with another concept, the perimeter, which is the measure of the figure’s contour (when we want to know the perimeter of a rectangle, we must add all its sides).
Geometric figures have a dimension that goes beyond mathematics. Proof of this is the art world, where the different artistic movements are inspired by concepts and geometric shapes, with Cubism being the most representative case in the history of art.
