关致尧回答:
  {详写的}   ```````````````````1.1立体图形   `````````````上底面```````````````下底面`````````侧面   ``````圆柱体圆形且与下底面相等圆形;平行于上底曲面,……   柱体:   ``````棱柱上下底平行…为多边形……都是矩形…   `````……………………   椎体:   `````……………………   `````……………………   台体:   `````……………………   球体:……………………   (把图形画上,再把你们学的内容填上就ok了.)   ````````````````1.2点线面   1.点(运动)→线(运动)→面(运动)→体   2.面面相交成线,线线相交成点.   3.旋转过程中图形的表面积与体积的变化情况.   ……   {展开与折叠……}   ````````````````1.3截一个几何体   1.球体(截面)——圆   2.圆柱→水平:…纵向:…斜切:…   柱体   棱柱→(同上)   3.椎体(同上…)   ````````````````1.4从不同方向看   1.主视图(高、长)   2.左视图(高、宽)   3.俯视图(长、宽)   ```````主视图```````左视图```````俯视图   球体   圆柱   圆锥   组成图   (把图形画上.)   `````````````````1.5平面图形   1.多边形   概念:……(图)   2.数多边形的边及三角形个数   (图)n(n-1)/2……   小结:   ````````````````````生活中的几何体   ``````````````````/````|````|````   ````````````````分类``展开`截面``视图   ````````````````````````|_____________|   ``````````````````````````````|   ```````````````````````````平面图形   ```````````````````````````(生活)   ps:居然不能空格…所以用“```”来保持美观…   (呼...累死我liao……)
