Each geometric shape has a unique name (ex. rectangle, square, oval, etc) and geometrical shapes can be easily identified by looking at an image and seeing the shape’s characteristics, such as number of sides, angles, curves, or points. In fact, geometric shapes are all around you all of the time. Figure 01 below shows examples of common 2D ...
- 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.
All faces are square in shape. A cube is a type of cuboid and is one of the 5 platonic solids. Octahedron. Octahedrons are a shape with 8 faces, 12 edges and 6 vertices. A regular octahedron has equilateral triangles for its faces, and is one of the 5 platonic solids. Dodecahedron. Dodecahedrons are a shape with 12 faces, 30 edges and 20 vertices.
Polygon. A quadrilateral is a polygon. In fact it is a 4-sided polygon, just like a triangle is a 3-sided polygon, a pentagon is a 5-sided polygon, and so on. Play with Them. Now that you know the different types, you can play with the Interactive Quadrilaterals. Other Names. A quadrilateral can sometimes be called:

In geometry, a shape can be defined as the form of an object or its outline, outer boundary or outer surface. Everything we see
Jul 15, 2024 · As the name suggests, curved 2D shapes are closed figures formed by purely curved lines or a combination of straight lines and curved lines. As discussed earlier, all curved 2D shapes are also considered non-polygons. The most common examples of such geometric shapes are circles, ellipses, arcs, sectors, segments, parabolas, and hyperbolas.
