解析 个. Angle sum of pentagon is degrees. A right angle is degrees. If a pentagon has right angles, the fifth would be degrees, which is impossible. So . 五边形内角和为度.一个直角为度.若五边形中有个直角,第五个角个度,但过不可能,所以只可有个直角....
If a certain number of points is connected by straight line segments, such that each point (also called vertex) is an endpoint of exactly two segments, a polygon is formed. However, if the vertices of a polygon are connected to other vertices (except the adjacent vertex) by segments, ...
