dar Forma A Nuestro Mundo: Las Figuras de Dos Dimensiones
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.
