load the attachmentsee the description of the constructionslider - $alpha$ -select the angleslider - point P - ruler with a socket, point Q must be line n

Why?

variable angle \alpha,

constant ruler (PT\infty\infty)and divider (PUQ) ,

slider (P) is cross-sectional variable angle and constant ruler and divider ( point Q on the line n)

Whether you are from the previous understand how it works proportions of angles, or that you explain step by step?

Attachmentson the ruler $AB\infty{_1}\infty{_2}$ , raises divider ADC where AB + AB = AC, ruler sets the angle $\alpha$semi-line ruler $B\infty{_1}$ sliding on point E , the point A of ruler slides semi-line l , when point C is on the line n , we get the radius of the circle , we get the angle $\beta$we have solved the tricection of any angleLook at the construction protocol , or find the error if there is ....

The classic trisection problem specifies tools as straightedge and compass only. Trisection using a ruler is not a problem.
