A triangle is a geometric figure classified as a polygon with three sides, three angles and three vertices, all in the same plane. The sides of the triangle are line segments that meet at their extremes. The triangle is a fundamental figure in geometry and has many practical applications, especially in engineering due to its rigidity and stability.
The five-pointed star, also known as the pentagram, is a geometric symbol consisting of a five-pointed figure made up of intersecting straight lines. This symbol has a rich history and many meanings in different cultures and traditions.
The pentagon is a common shape in nature and art, often associated with the golden section, which is considered aesthetically pleasing. In addition, the regular pentagon is the basis for the construction of the pentagram, a five-pointed star that has symbolic meanings in various cultures.A pentagon is a flat geometric figure (a polygon) that has five sides and five angles. The word 'pentagon' comes from the Greek, where 'penta' means five and 'gono' means angle.

Instructions Now that you've mastered the basics, create a complex figure by combining several figures. Tips Experiment with combining different movements and angles. Use 'repeat' blocks to simplify your code. Share your creation with colleagues! General Tips Test your code: Every time you program a figure, test it to see if it works correctly. Correct mistakes: If something doesn't work as expected, check the angles and movements. Collaborate: Work as a team and help your colleagues if they have questions. Have fun: Programming is like solving a puzzle - enjoy the challenge!
A circle is a geometric figure defined as the set of all points on a plane at a fixed distance, called the radius, from a central point, called the centre. It is one of the simplest and most basic shapes in geometry.
Draw a square
In the first video we see how we can draw a square with step-by-step instructions, where we end up repeating the same instruction several times, and in the second video we draw a square with fewer instructions, where we indicate by repetition how many times the instructions are repeated.
To draw a complex figure using elementary geometric shapes such as a square and a triangle, in this case we're going to use 2 functions, one for the square and one for the triangle, in order to use them in the iteration cycle and make the code more readable.
A hexagon is a flat geometric figure (a polygon) with six sides and six angles. The word 'hexagon' comes from the Greek, where 'hexa' means six and 'gono' means angle; to draw a hexagon, the angle of rotation is 60 degrees (360° ÷ 6 sides).The hexagon is a very space-efficient shape, which is why it is often found in nature, such as in honeycombs. It allows you to cover an area without leaving any empty spaces!
An octagon is a flat geometric figure (a polygon) with eight sides and eight angles. The word 'octagon' comes from the Greek, where 'octo' means eight and 'gono' means angle. Each external angle measures 45°.
A heptagon is a polygon with seven sides and seven angles. The term 'heptagon' comes from the Greek 'hepta', meaning 'seven', and 'gono', meaning 'angle'. To calculate the angle of rotation needed to draw a heptagon, use the following formula:
