That property is still true even if the center of the circle has been moved out after the point D to point G?

If you are using Kig, you got an option of "intersection" that will draw the point of intersection. It is easier and error free.

I did it in Kig (Interactive Geometry) and always works.
I just have to prove it.

AF = 6.30
BC=6.23
That will not be the error?

Hi Bob
In some cases like that are 6 points.

This well done. I could put names to the points?

Measure the segment AB and draw a circle at center C
Measure the AC segment and draw a circle in center B
Measure the segment CB and draw a circle in center A

Testing ...
Do I have to wait to upload an image that is completely or just subis you can post?

Hello mathematicians.
I found an easier way of construction of similar triangles.
I'm still seeing in relation to the building or if the relationship is either.

Here's the procedure:
1) Draw the triangle ABC.
2) Taking the measure of segment AB and draw a circle in C
3) Taking the measure of segment BC and draw a circle at
4) Taking the measure of segento CA and draw a circle in B
5) After this, you are 3 circles with 9 points of intersection. Joining of three points, the right way, you are 3 similar triangles.

Oh, and something else. I have to prove but I can use what I had found earlier for construction of similar triangles. For now I let them try and see how fun and crazy it is drawing similar triangles using ruler, pencil and compass.

I hope they serve to help or interest to them.

Hi Bob bundy.
I was down to 100kb but nothing happened.

Thanks anonimnystefy

Thanks Bob Bundy
Asked because I found a method to draw three triangles similar to an extent that they have a special relationship within the interior angles of the first triangle.
How sould upload a picture to show you an example?
