Lux Squares and Trigons

Lux Blox have two main pieces: a square-shaped piece called a Lux Square and a triangle-shaped piece called a Trigon. These pieces can be connected to create many different shapes and designs. ## Lux Blox

Measuring 2D Shapes

The perimeter is the outline of a 2D shape.

When you measure the perimeter of a polygon or 2D shape, you have to calculate how long (length) and tall (height) all the sides of the shape are. If you add all the sides of a regular polygon together, you get the perimeter.

Area of a 2D Shape

The area is the inside of a 2D shape.

When you measure the area of a polygon or 2D shape, you have to calculate what is inside the shape. If you multiply the length and the height of a regular polygon together, you get the area. After you figure out the area, you will write the units of your answer with a small number 2 at the end to show that you multiplied inches by inches. Another way to say inches x inches is inches "squared" or inches2.
