The segments are called edges or sides, and the ends of the sides are called vertices or corners of the polygon.Ī polygon is crossed if at least two nonconsecutive sides intersect and simple if the intersection of two sides is empty or reduced to a vertex for two consecutive sides. The polygon is the two- dimensional case of the polytope. These segments are called sides, and the intersect points are called vertices. In geometry, polygons are two-dimensional geometric shapes composed of a finite sequence of consecutive straight line segments enclosing a region in the plane. In both cases, we are dealing with closed curved lines. The curved shapes are the circle and the ellipse in the list of shapes above.
The curved geometric shapes are the figures that can be represented on a flat surface in which at least one of its sides is a curved line. A regular pentagon is a pentagon where all sides and angles are equal.Ī pentagon is a polygon with six sides, angles, and vertices. Trapezoid is a quadrilateral polygon in which none of the opposing sides is parallel.Ī pentagon is a polygon with five corners. Trapezoid is a polygon with four sides of which two of the opposite sides are parallel. Like the square, the angle formed by the edges that touch is 90 degrees.Ī rhombus is a quadrilateral in which all four sides are equal, and the angles are equal two by two.Ī rhomboid is a quadrilateral with two pairs of equal sides. Sides are equal two by two: sides of the same length are parallel. The rectangle is a geometric shape formed by four edges. The square is a quadrilateral formed by four sides with equal length and equal interior angles (90 degrees). Since it is effortless to calculate the triangle's area, it is an interesting way to calculate any polygon's area. This shape is fascinating because all polygons can be split into triangles. Scalene triangle: The three sides of the triangle are different. Isosceles triangle: It only has two equal sides. It comprises three sides, three vertices, and three angles.ĭepending on their angles, there are three types of triangles: equilateral, isosceles, and scalene.Įquilateral triangle: It has three equal sides. The triangle is the simplest polygon that can be represented. The main characteristic of the ellipse is that the sum of the distance from a point to one of the foci with the distance from the same point to another of the foci is always constant. The ellipse is a geometric figure formed by a curved line with centers called foci. Also, all points on this curved line are the same distance from a center point. It is a circular sector in which the ends are connected. The circle is made up of a single circular segment. Here is a basic list of 2D shapes with their name, a drawing, and a brief description, of the main named regular geometric figures: The branch of mathematics that studies geometric shapes is geometry. An example of a solid shape is the cube, which is a shape that has 12 edges, eight vertices, and six faces. These 3d shapes occupy a volume in space. In contrast, solid shapes are the shapes represented in a three-dimensional space. Polygons are those types of geometric shapes that are bounded by straight lines. These elements are composed of straight and curved lines connected, for example, the circle, the square, or the triangle. Flat geometric shapes are spaces delimited by flat surfaces.
