When did geometry appear?

-


Hello guys! As my first post, I will give you some information about geometry origins :).

Geometry appeared because of the studies of mathematicians in order to understand shapes or space measures. This primitive type of geometry emerged in the ancient Egyptian civilisation, Babylon and it was improved by the Greek population. In the sixth century B.C, a mathematician called Pythagoras, started to develop different types of laws that explained a huge number of questions such as Pythagoras theorem. This theorem shows that the squared hypotenuse of a right triangle is equal to the sum of its remaining sides squared. 

Euclides was a Greek mathematician who wrote a book about polygons, circles and their three-dimensional figures. The book was called The elements and this text has been a geometry reference through history until nowadays. 



The first geometry problems were introduced as the population needed to find out solutions in order to have an effective building construction. Greek population studies lines, curves, different types of polygons and also they started to create some ways to achieve the areas of different figures.


Here in this video you can access to more information about the origin of geometry:






As a curiosity, Greek population did not have any instruments in order measure the different figures or spaces that they needed to so they had 

different measures units: 

  • Daktylos was equivalent to the width of one finger.

  • Kondylos was equivalent to the width of two fingers.

  • Palame was equivalent to the width a hand 

  • Pechys was equivalent to the distance from the elbow to the hand.

  • Pous was equivalent to a foot.


What do you think about these primitive measure units? 

I hope you have learnt more about geometry in this first post, I will see you soon!!

Let's practice length exercises!

  Hello guys! In today’s post I am going to talk about length and how to work with it in a classroom.  First of all, length is a physic magnitude which we measure the distance between two points with. Its principal unit of measure is the metre but it is composed by this units:  This is the metre scale, we use this as stairs because it is more visual and easy to remember for the kids. Each step is a change of measure, when the steps are for going up, the measure loses quantity but when the steps are for going down, the measure acquires quantity. In order to understand this scale, kids only have to think as if they were going up or down stairs, this way they will easily remember the different calculations that they have to carry out.  In order to practise length exercises, here you can find some examples depending on the difficulty level:  Level 1:  Peter’s pencil measures 15 centimetres. Ana’s pencil measures 10 centimeters. How much longer is Pedro’s pencil...

Did you know about triangle different meanings?

Hello everybody!  As my second post, I have created a presentation about a curiosity of the triangles. These shapes have developed a very important role during history because the first studies of the triangles began 3000 years ago.  There are plenty of studies about triangles as it is a very interesting figure because it has a lot of areas that can be studied. Also, this shape is the protagonist of different theorems so it presented many challenges to mathematics along the history of maths. For this reason, triangles has been given different kind of meanings during all this years, would you like to know them? Here you can access to the presentation:  https://www.canva.com/design/DAGkH0Dj8q8/W4_foUvc9YojYNCZMAf6BQ/edit?utm_content=DAGkH0Dj8q8&utm_campaign=designshare&utm_medium=link2&utm_source=sharebutton Here you can find a video about triangles' meanings:  That is all for today. Thank you so much, I will see you soon! References:  Bravo, D. (2023)...

Symmetry and iconic buildings.

 Hello guys! Today's post will be about how geometry has influenced the creation and construction of several emblematic buildings during history.  From the ancient civilizations to modern skycrapers, architecture has been always a tangible expression of geometry. Shapes, proportions and symmentires not only beautify the strucuture but also define its stability and function. Geometry has been used foe centuries to create structures that are balanced and resistant, it is not a coincidence that many of the most admirable buildings in the world are based on geometric principles.  Here you can see some examples:  The Eiffel Tower in Paris.  This ionic building situated in France, is a clear example of axial symmetry which means that if you write a line in the middle of the monument, each part would be almost identical. This parts are called mirror images because it is represented as a mirror reflection.  How can we show the symmetry of the Eiffel Tower in class?...
