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 五角大楼 三角形 形状 几乎一个五边形
I've discovered new shapes which are just like regular polygons, except with round sides! This is the pentagon example 圆 五角大楼 五角星 圆五边形
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 圆圈 六角 内部 多边形内圈
