ART AND GEOMETRY

REGULAR POLYGONS

Our first Technical Drawing Activity will be a mandala done with regular polygons. Here are a few tutorials to refresh your knowledge about the Regular Polygons' constructions.





THEORY FOR THE NOTEBOOK 





Lets see now how to draw regular polygons inscribed in a circumference:



REGULAR POLYGONS GIVEN THE SIDE:





ACTIVITY: REGULAR POLYGONS MANDALA

Let´s pratice the Geometrical Constructions we have learnt by designing our own MANDALA.

FIRST DO A PRACTISE IN NORMAL PAPER 

STEPS: 
1- In the center of a normal paper you draw a circumference 8 cm radius.
2- Then you divide the circumference in equal parts (7,8,9,11...).
3- You draw regular polygons, depending on the parts you divided the circumference. For example: if you divided it in 8 equal parts you can do a star octagon or an octagon, if it was 11 an hendecagon, and so on...

THEN THE FINAL MANDALA IN THE DRAWING PAPER (BASIK PAPER)

In the drawing paper you will repeat the previous steps and then trace the lines with felt-pens and colour the mandala with colour pencils, feltpens, crayons, pastels, water-colour or temperas. 

YOU WILL HAND IN THE BOTH THE PRACTISE AND THE FINAL WORK
