this is as close as you can get making a pentagon with triangles that don't overlap, that is with them pointing inward towards the center 五角大樓 三角形 形狀 幾乎一個五邊形
I've discovered new shapes which are just like regular polygons, except with round sides! This is the pentagon example 圓 五角大樓 五官 圓五邊形
I was looking in a geometry book at the library and saw regular polygons inside circles. I was curious to see how it works in inkscape. It's actually very easy with inkscape's polygon tool. If you create any regular polygon, then snap it to the center of a circle, then you can snap the 1 node to one of the four orthagonal snap points 圓圈 六角 內部 多邊形內圈
