, otherwise it is irregular. Teachers begin teaching about shapes at an early age, so students can develop an almost intuitive feeling for recognizing the different shapes at higher grade levels. This excitement usually begins with first-grade geometry when the students draw and label 2-D shapes. Some 2-D shapes include rectangles, squares, trapezoids, triangles and circles. The Different Kinds of Shapes in Math Sciencing What is a Polygon? Definition of a Polygon. A polygon is any 2-dimensional shape formed with straight lines. Triangles, quadrilaterals, how to reduce stress in daily life pentagons, and hexagons are all examples of polygons. The name tells you how many sides the shape has. For example, a triangle has three sides, and a quadrilateral has four sides. Preschool Worksheets Kindergarten Worksheets. Shapes, circle, Triangle, Square, Rectangle, Rhombus, Oval.

- An irregular pentagon is a shape that does not have equal sides and/or angles and therefore do not have specified angles. More than Four Sides. A five-sided shape is called a pentagon. A six-sided shape is a hexagon, a seven-sided shape a heptagon, while an octagon has eight sides.
