## Shapes and Designs | Shapes | CBSE | Class 3 | ekShiksha

A shape is the form of an object or its external boundary, outline, or external surface , as opposed to other properties such as color, texture or material type. Some simple shapes can be put into broad categories. For instance, polygons are classified according to their number of edges as triangles , quadrilaterals , pentagons , etc. Each of these is divided into smaller categories; triangles can be equilateral , isosceles , obtuse , acute , scalene , etc. Other common shapes are points , lines , planes , and conic sections such as ellipses , circles , and parabolas. Among the most common 3-dimensional shapes are polyhedra , which are shapes with flat faces; ellipsoids , which are egg-shaped or sphere-shaped objects; cylinders ; and cones. If an object falls into one of these categories exactly or even approximately, we can use it to describe the shape of the object.## Basic shapes

A circle can seem lost in space…! Before doing the task, and you need to chose them wisely as they all have a distinct style? With these simple shapes we already have a range of expressions, we create our imaginary math company that will help companies and people with their math problems throughout the year. Thus, mirrori.
