1、课堂练习：1.如图所示，正六边形ABCDEF 内接于 O，则ADB 的度数是（）A60B45C30D 2252.圆内接正五边形 ABCDE 中，对角线 AC 和 BD 相交于点 P，则APB 的度数是（）A36B60C72D 1083.正十二边形每个内角的度数为.4.如果一个正多边形的一个内角为144,则这个正多边形的边数为.5.比较正五边形与正六边形，可以发现它们的相同点与不同点.相同点：（1）_;（2）_.不同点：（1）_;（2）_.课后练习：1.如图，点O是正六边形的对称中心，如果用一副三角板的角，借助点O（使该角的顶点落在点 O处），把这个正六边形的面积n 等分，那么n 的所有可能取值
2、的个数是（）A.4 B.5 C.6 D.7 2如图，正三角形ABC 内接于圆 O，动点 P在圆周的劣弧 AB 上，且不与 A，B 重合，则 BPC 等于A.30oB.60oC.90oD.45o文档编码:CY3A4I10K5K6 HZ9M2A10N4B2 ZY6V6S3D5R9文档编码:CY3A4I10K5K6 HZ9M2A10N4B2 ZY6V6S3D5R9文档编码:CY3A4I10K5K6 HZ9M2A10N4B2 ZY6V6S3D5R9文档编码:CY3A4I10K5K6 HZ9M2A10N4B2 ZY6V6S3D5R9文档编码:CY3A4I10K5K6 HZ9M2A10N4B2 ZY6V6
