## Elementary Geometry – Open Lines In this post, we are going to discover what an open line is and how it is different from a closed line. We will also see different types of open lines. Before we begin, take a look at this post about straight and curved lines to refresh your memory. Open Lines We know that a […]

## Identifying Flat Symmetrical Figures In today’s post, I am going to present a series of exercises to practice how to identify flat symmetrical figures. To begin, I recommend that if you don’t remember symmetry or the characteristics that make a figure symmetrical very well, take a look at this previous post. You’ll be able to review all of the […]

## How to Calculate a Perimeter: Part 2 In an earlier post, we learned how to calculate the perimeter of any polygon and formulas for regular polygons and rectangles. Today, we are going to learn how to calculate the perimeter of other types of polygons: rhombuses, isosceles triangles, isosceles trapezoids, and stepped polygons. NOTE TO OUR READERS IN THE U.K. – This post […]

## Calculating the Area of Polygons In today’s post, I am going to show you some exercises we have recently incorporated into Smartick for calculating the area of polygons. For some time we have had exercises to practice the area of figures with small squares. The way to calculate the area of these figures is very simple because all you have […]

## What Is an Angle? How Is It Made? In today’s post we are going to answer the question, what is an angle? To begin, it would be a good idea for you to review the following link where we have explained the concept of ”straight lines.” Types of Lines Now that you remember straight lines, let’s begin! In order to understand what an […]

## Do You Know What a Right Angle Is?

You probably already have some idea about what we call a right angle. But, I still would recommend taking a look at some other posts on our blog before continuing, for example, you can review this post about the different types of angles. Are you ready? Well, let’s expand your knowledge about right angles. Imagine […]

## How to Calculate Perimeters: Part 1 Today we are going to learn to calculate perimeters of geometric figures. But first, let’s start with the definition of a perimeter. When we say perimeter we are referring to the length of the polygon’s outline. Here you can review the most common types of polygons. The length of a polygon’s outline can be calculated […]

## Trapezium-Trapezoid: Definition, Types and Exercises In today’s post, we are going to study a bit of geometry. We will focus on one flat figure: the trapezium (UK – trapezoid).   There is considerable confusion over the definition of ‘trapezoid’ and ‘trapezium’ due to differences in the British and US versions. As you can see from the table above, the meanings […]

## Left and Right, Is It as Easy as It Seems? In today’s post, I am going to show you how to learn to distinguish between left and right, as well as some Smartick activities to practice these concepts. It is a simple concept but can be complicated, let’s see why. Left and Right They can be represented graphically: Is very easy this way, right? At Smartick, […]

## What Are Solid Geometric Shapes or Bodies? Surely, you know about flat geometric figures so today we are going to talk about solid geometric figures which are also known as geometric shapes or bodies. These figures have three dimensions – length, depth, and height. In other words, these figures have volume and we can say that they occupy a place in space. […]
