# Geometry

#### A lot of geometry contents for Primary schools are now available online.

Learn the different shapes and how to calculate the perimeter and the area of figures.

## How to get your bearings

Where is the exit? Who is the person in front of you in your classroom? How many things did you put in your backpack? Learn how to get your bearings, discover the directions: right, left, up, down, in front of, behind. Learn the difference between inside and outside!

## Space and shapes

What can you draw on paper? Learn how to identify plane shapes and solid shapes. Let's make the first steps in geometry: learn about lines, polygons and solids.

## Plane geometry

What are the main elements of plane geometry? Discover lines, half lines and line segments. Learn the characteristics of parallel lines and perpendicular lines. What is an angle? Learn how to identify all the different types of angles.

## Polygons

What are polygons? Discover all the properties of polygons, quadrilaterals and triangles and learn to classify them by sides and angles.

## Perimeters and areas of polygons

When you have to solve a geometry problem, you are often asked to find the perimeter and the area of figures. In this chapter you will learn all the formulas that you need! Discover the perimeter and the area of squares, rectangles, triangles, trapezoids, regular and irregular polygons.
