Plane shapes are all around us, but how do we know what shapes are plane shapes? In this lesson, you will learn what plane shapes are and explore their different types and properties.

What are Plane Shapes?

Plane shapes in mathematics are any closed, flat, 2-dimensional shapes. Let's take a look at some shapes:

As you can see, the plane shapes in the top row include a triangle, rectangle, diamond, and star. The plane shapes in the bottom row include a pentagon (or a 5-sided shape), circle, and square.

Now take a minute to see if you can find some shapes around your house that are plane shapes. These might include a clock, dinner plate, piece of paper, or rug.

Types of Plane Shapes

Did you know there are different types of plane shapes? For instance, many plane shapes are polygons, or any 2-dimensional shape with straight sides or lines that is closed and has no open sides. Let's go back and take another look at the image of the plane shapes and see if any of these shapes are polygons.

That's right; the triangle, rectangle, diamond, star, pentagon, and square are all polygons.

Another type of plane shape is known as a quadrilateral, or a 2-dimensional shape with 4 straight sides that is closed and has no open sides. Let's look at some examples of quadrilaterals:

As you can see, some plane shapes are both polygons and quadrilaterals.

Now see if you can find any quadrilaterals around your house. For example, a photo, a square tile on your kitchen floor, or a place mat on your table would all be considered quadrilaterals.

Properties of Plane Shapes

Plane shapes have properties including sides, corners, and faces. Do you see any of these properties in this image of a rectangle?

Properties of a Rectangle

The easiest way to find the properties of a shape is to think about it sides first, then its corners, and finally its flat surface, or face. For example, a rectangle has the following properties:

  • 4 sides
  • 4 corners
  • 1 rectangular face
