How to divide a circle in three halves

First of all draw a circle (with the SHIFT key), color does not matter (preferably not green, because the color of the guide line is the default color green!) Because we have to change it later. Drag a green locator line from the top and left rulers (add: first show the ruler "View-->rules" and then click the mouse on the ruler to turn the mouse into a double-headed arrow, and don't loosen the mouse when you stop it. Down or to the right, the corresponding guides are dragged separately. The two guides intersect at the center point of the Circle (note: You can refer to the four path nodes of the circumference). (Small tip: After drawing a circle, you can use the Super selection tool to drag out the guidance line, the effect will be more ideal, you can try it yourself!) ）

Select the Polygon tool for the rectangular tool Group of the Toolbox and make the appropriate settings in the option panel. "Shape" selects "Star", "sides=3", "angle=1 or 2". All set OK, put the mouse to the center of the guide, press the mouse, while holding down the "SHIFT" button, drag the mouse to the top, until the end of the Triangle star from the edge of the circle around 10px. This time you actually have this round three equal! ：）

Next, select the menu item "edit--> Select All" (or CTRL + A CAN), then "Modify--> combine--> Punch". But, now with the mouse click, Circle or a whole ah? Don't worry, there is a final step, but also the most critical step! Select the menu item "Modify--> Split". Oh, see what, three fan is evenly cut off. Because we have just used the triangular star to do the cutting, the inevitable in the center produced a gap, at this time we need to make a small adjustment, the gap is excluded, otherwise it would be too ugly: (. At this point, we have a very simple way, you can enlarge the graphics several times to operate, such as in the 400% view of the operation, select the toolbox of the Super Selection tool, in the center of the central section of each sector selected center point to drag the center of ... Oh, everything looks so perfect!

Well, fill your favorite color, and finally, remember the full selection, and then "Modify-->group", or you work hard to do the job by your casual mouse waving will be pieces ... Hehe:) Add a nonsense: In fact, this dongdong used to make a statistical map is the most appropriate!
