Dividing a line segment into equal parts

Let’s start by drawing our name with a lot of creativity.

To perform this exercise you must learn to divide a segment into equal parts. But warning! it is very important to know how to do parallel with square and bevel.

Here you can see how to do parallels.

Last year we did a very nice job applying it to making your name. We are going to do a brief review and we are going to apply it to the construction of regular polygons.

The order you have to follow to watch the videos is as follows:

1. Thales Theorem

2. Doing a margin on the sheet (opcional)

3. Second task : Divide a segment

4. General Method

Perpendicular bisector

Dot

Marcos Salvador Romera is a Murcia painter who made an exhibition at the Almudí Palace about the circus. Use the dot, the line and the plane, in a very simple way to create very descriptive and attractive images of the circus world.

We will use the temperas to create a  similar world  to the one created by this painter, using the primary and secondary colors, to create flat shapes and silhouettes such as circus tents, clowns, faces, etc. and then give them more dynamism and strength overlapping dots and lines.

Finally, I’ve uploaded the works that students made. Enjoy them.
