(2)PE⊥AB于E,PF⊥AC于F,M为EF的中点,∠BAC=90°,∴四边形AEPF是矩形,点M是EF和AP的中点,∵点A到线段BC的最小值是AP⊥BC时取得,∴当AP⊥BC时,AP=AB∙ACBCAB•ACBC=4.8,∴此时,AM=12AP12AP=2.4;故答案为:(1)90;(2)2.4. 点评 本题考查勾股定理的逆定理、垂线段最短、矩形的判定和性质,...
如图,在四棱锥P-ABCD中,PD⊥平面ABCD,PA⊥PC,底面ABCD为菱形,G为PC中点,E、F分别为AB、PB上一点,△BCE的面积为63,AB=4AE=42,AC=46,PB=4PF. (1)求证:AC⊥DF;(2)求证:EF∥平面BDG;(3)

分析 根据三个角都是直角的四边形是矩形,得四边形AEPF是矩形,根据矩形的对角线相等,得EF=AP,则EF的最小值即为AP的最小值,根据垂线段最短,知:AP的最小值即等于直角三角形ABC斜边上的高. 解答 解:∵在△ABC中,AB=3,AC=4,BC=5,∴AB2+AC2=BC2,即∠BAC=90°.又∵PE⊥AB于E,PF⊥AC于F,∴四边形...
It will be recalled that an electrical charge consists of a surpIus of electrons (negative charge) or a deficiency of electrons (positive charge). Like charges repel-there is a mutual repulsion among electrons-while unlike charges attract.P. F. LeonardAnesthesia & Analgesia...
