The world around us is made up of so many shapes and sizes, right? That’s why it’s so important to understand how to identify shapes, figure out how big they are, and more. DoodleMath has the resources you need to master your shapes and build a successful base for more challenging subjects like geometry and calculus later on.
Practice makes perfect. Work through practice problems or use our guides to refresh your mind and master your shapes!
Explore the world’s “perfect” shapes.
Discover all the different types of triangles.
Learn why a square is always a rectangle, but a rectangle is not always a square.
Play around with multi-sided shapes, like hexagons and more!
Go 3D with spheres, cubes, and prisms.
Figure out how big those shapes really are.
Learning about shapes and the properties of shapes would be a lot easier if it was all about memorization. However, there’s so much more to shapes than just their names. Explore our guides and games to grow your knowledge about important concepts like area, perimeter, and more.
Already have questions? Maybe we can answer a few! Here are the most commonly asked questions we get about shapes.
The four main shapes are circles, triangles, squares, and rectangles. Of course, there are shapes outside of these, including three-dimensional shapes like spheres, cones, and cubes, but these are considered the four main shapes.
You might think it’s one of the four main shapes, but the most common shape in nature is actually the hexagon. Beehives, insect eyes, snowflakes and more are all made up of hexagons, which fit together seamlessly.
The golden spiral is a geometric shape that resembles a snail shell and that perfectly captures the Fibonacci sequence. The Fibonacci sequence is a sequence where each number in the sequence is equal to the sum of the two numbers preceding it, so: 0, 1, 1, 2, 3, 5, 8, etc.
Perimeter is the measure of the outside of a shape, which you can get when you add together the lengths of each of its sides. The area is the inside of a shape. Each shape has its own area equation.
