Rectangle is another quadrilateral with 2 lines of symmetry. Square is a quadrilateral with 4 equal sides and four right angles. This is a group consisting of a variety of members. Quadrilaterals – It is a close figure possessing 4 sides. Acute triangle is the triangle whose all angles are acute. Obtuse triangle is the triangle whose one of the angles is greater than 90 degrees, whereas the other two angles measure less than 90 degree. It also includes a right angle triangle whose one of the angles is a right angle or of 90 degrees. Scalene triangle is the triangle which has no equal sides and no equal angles. Isosceles is another type of triangle which has 2 equal sides and 2 equal angles. There are many different types of triangles like equilateral triangle with all sides equal in length and 3 equal angles of 60 degrees. Triangles – These are shapes characterized by three sides. A polygon with all sides and angles same is known as a regular polygon, and if not then it is termed as an irregular polygon. Here the one dimension term refers to length.Ģ Dimensional shapes (shapes with length and breadth) – A plane 2 D shape with straight lines and no curves is known as a polygon. Line – The category of 1 dimensional shapes includes shapes with only lengths. These geometrical shapes can be classified into following categories –
These geometric shapes provide the geometric location which excludes the factors like orientation, scale, location and reflection. Shapes in context to geometrical shapes lie in the concepts of plane and solid geometry. Shape defines the external boundary or surface of an object. Commonly, shapes are divided into three categories – 1, 2 and 3 dimensional shapes.
Key Difference: Geometrical shapes cover all basic shapes like lines, polygons and simple curves.
