註釋Shapes are everywhere you look. They are in the streets, in your classroom, and in your home. Two-dimensional (2-D) shapes have length and width. Regular 2-D shapes have angles (which are measured in degrees °) that are all equal, and irregular shapes have angles that are not equal. Shapes can create different patterns. You can discover the different types of 2-D shapes and patterns as you look around you.
