the picture is<br>
-circle<br>
-diameter circle AB<br>
-points on the diameter of the circle A(0°),B(180°), C (AD=DC=CB) , D , F(center of the circle ,FB-radius circle)<br>
-tendon EF<br>
<br>
I went from the assumptions that there are lines in a circle which is the first point (180 °> point> 0 °), the last point is (360 °> point> 180 °) to the intersection with the circle diameter (AB) be the point C (D).<br>
I shared a circle with corners (second part , 9 to 23).<br>
I found the string (EF, 3.75 ° -187.5 °) which passes through the point C ,which means that we have the angle trisection.<br>
