A geometrical shape is a structure that has a definitive shape comprised of curves, lines, and/or points. You are probably already familiar with many common 2D geometric shapes like circles, ovals, squares, and rectangles, in addition to common 3D geometric shapes such as cubes, spheres, and cylinders.
- Ellipses. Ellipses are round, oval shapes in which a given point (p) has the same sum of distance from two different foci. Oval. An oval looks a bit like a smooshed circle—rather than being perfectly round, it's elongated in some way.
- Triangles. Triangles are the simplest polygons. They have three sides and three angles, but they can look different from one another. You might have heard of right triangles or isosceles triangles—those are different types of triangles, but all will have three sides and three angles.
- Parallelograms. A parallelogram is a shape with equal opposite angles, parallel opposite sides, and parallel sides of equal length. You might notice that this definition applies to squares and rectangles—that's because squares and rectangles are also parallelograms!
- Trapezoids. Trapezoids are four-sided figures with two opposite parallel sides. Unlike a parallelogram, a trapezoid has just two opposite parallel sides rather than four, which impacts the way you calculate the area and perimeter.
Here you will find a list of different geometric shapes to help you to identify a range of 2d and 3d shapes. Along with each shape, we have also included the properties of each shape and other helpful information.
Our page on Polygons covers shapes made with straight lines, also known as ‘plane shapes’. This page explains more about shapes with curves, especially two-dimensional ones. Two-dimensional curved shapes include circles, ellipses, parabolas, and hyperbolas, as well as arcs, sectors and segments.
Properties. A quadrilateral has: four sides (edges) four vertices (corners) interior angles that add to 360 degrees: Try drawing a quadrilateral, and measure the angles. They should add to 360°. Types of Quadrilaterals. There are special types of quadrilateral: Some types are also included in the definition of other types!

A geometric shape is any structure, open or closed, having a definite shape and properties made up of lines, curves, and points. Some of the known geometric shapes are square, rectangle, circle, cone, cylinder, sphere, etc. All these shapes have some properties that make them unique and different from the other shapes.
