A polygon can be any number of shapes. A polygon is a two dimensional shape made of at least 3 straight lines that do not cross and is a closed shape. Examples of polygons would include triangles, squares, rectangles, he...
An irregular polygon is any polygon where all sides and all interior angles are not equal. An polygon can be an irregular polygon regardless of how many sides it has.
Triangles, squares, rectangles, pentagons, hexagons and octagons are some of the most common polygons. A polygon is a plane figure with many sides made up of line segments.
A quadrilateral is any two-dimensional shape or polygon that has four straight sides. A quadrilateral can also be called a quadrangle or a tetragon.
An inscribed polygon is a two-dimensional shape contained entirely within a circle. The points of each corner are on the circumference of the circle. Inscribed polygons have other special geometric properties.
To calculate the area of an irregular shape, the shape needs to be divided into regular shapes that can have their area easily calculated; the area of the regular shapes can be added up to equal the total area of the irr...
Teach shapes to children by making a shape collage, drawing shapes on the sidewalk with chalk and sorting household items by shape. For a shape collage, cut paper into different shapes and sizes, and encourage the child ...
