【答案】D【解析】由不共线的三点确定一个平面，故A错误；由一条直线和该直线外一点确定一个平面，故B错误；当圆心和圆上两点在圆的直径上，不能说明该三点确定一个平面，故C错误；由于梯形是有一组对边平行的四边形，可得梯形确定一个平面，故D正确．故选：D．【知识点】平面向量的概念与表示4. 【答案】A【解析】因为i2=−1，所以1+i2=0．故选：A．【知识点】复数的乘除运算5. 【答案】A【解析】a⃗⋅b⃗⃗=∣a⃗∣∣b⃗⃗∣cosπ3=1×2×cosπ3=1．【知识点】平面向量的数量积与垂直6. 【答案】A【解析】因为a⃗∥b⃗⃗，所以1×1−xy=0，即xy−1=0．【知识点】平面向量数乘的坐标运算7. 【答案】A【解析】在平行四边形ABCD中，因为 A (1,2)，B (3,5)，所以 AB⃗⃗⃗⃗⃗⃗=(2,3)， 又 AD ⃗⃗⃗⃗⃗⃗=(−1,2)， 所以 AC ⃗⃗⃗⃗⃗⃗=AB ⃗⃗⃗⃗⃗⃗+AD ⃗⃗⃗⃗⃗⃗=(1,5)，BD ⃗⃗⃗⃗⃗⃗⃗=AD ⃗⃗⃗⃗⃗⃗−AB ⃗⃗⃗⃗⃗⃗=(−3,−1)， 所以 AC ⃗⃗⃗⃗⃗⃗+BD ⃗⃗⃗⃗⃗⃗⃗=(−2,4)， 故选A ．【知识点】平面向量和与差的坐标运算8. 【答案】A【解析】 BC ⃗⃗⃗⃗⃗⃗+CD ⃗⃗⃗⃗⃗⃗=BD ⃗⃗⃗⃗⃗⃗⃗=AD

所以 sinA+C 2=2sinA+C 2cosA+C 2，因为 0<A +C <π， 所以 0<A+C 2<π2．所以 sinA+C 2≠0，cosA+C 2=12，A+C 2=π3，所以 A +C =2π3，B =π−(A +C )=π−2π3=π3(2) 由正弦定理得 asinA =bsinB =csinC =2sinA ， 所以 c =2sinC sinA，由三角形内角和知 A +C =120∘， 所以 C =120∘−A ， 所以 c =2sin (120∘−A )sinA=√3tanA+1，又 △ABC 为锐角三角形， 所以 120∘−A <90∘ 且 A <90∘， 即 30∘<A <90∘， 又 S △ABC =12acsinB =12ac ×√32=√32c =√32×(√3tanA +1)，30∘<A <90∘，因为30∘<A<90∘，所以tanA>√33，得√3tanA <3，即1<√3tanA+1<4，所以S△ABC=√32×(√3tanA+1)∈(√32,2√3)．【知识点】正弦定理18. 【答案】（1）在已知的直角梯形OBCD中，以OB所在直线为x轴，垂直于OB的腰OD所在直线为y轴建立平面直角坐标系．画出相应的xʹ轴和yʹ轴，使∠xʹOʹyʹ=45∘，如图①②所示．（2）在xʹ轴上截取OʹBʹ=OB，在yʹ轴上截取OʹDʹ=12OD，过点Dʹ作xʹ轴的平行线l，在l上沿xʹ轴正方向取点Cʹ，使得DʹCʹ=DC．连接BʹCʹ，如图②所示．（3）所得四边形OʹBʹCʹDʹ就是直角梯形OBCD的直观图，如图③所示．【知识点】直观图19. 【答案】画法：（1）在图①中作AG⊥x轴于G，作DH⊥x轴于H．（2）在图②中画相应的xʹ轴与yʹ轴，两轴相交于点Oʹ，使∠xʹOʹyʹ=45∘．（3）在图②中的xʹ轴上取OʹBʹ=OB，OʹGʹ=OG，OʹCʹ=OC，OʹHʹ=OH，yʹ轴上取OʹEʹ=1 2OE，分别过Gʹ和Hʹ作yʹ轴的平行线，并在相应的平行线上取GʹAʹ=12GA，HʹDʹ=12HD．（4）连接AʹBʹ，AʹEʹ，EʹDʹ，DʹCʹ，并擦去辅助线GʹAʹ，HʹDʹ，xʹ轴与yʹ轴，便得到水平放置的正五边形ABCDE的直观图五边形AʹBʹCʹDʹEʹ（如图③）．【知识点】直观图20. 【答案】(1) 点P∈直线AB．(2) 点C∉直线AB．(3) 点M∈平面AC．(4) 点A1∉平面AC．(5) 直线AB∩直线BC=点B．(6) 直线AB⊂平面AC．(7) 平面A1B∩平面AC=直线AB．【知识点】点、线、面的位置关系、直线与平面的位置关系、平面与平面的位置关系、直线与直线的位置关系21. 【答案】构成三棱锥，这6条线段作为棱有两种摆放方式．（1）2条长为a的线段放在同一个三角形中．如图所示，不妨设底面 BCD 是一个边长为 2 的正三角形．欲使体积达到最大，必有 BA ⊥底面BCD ，且 BA =2，AC =AD =a =2√2， 此时 V =13×√34×22×2=23√3．（2）2 条长为 a 的线段不在同一个三角形中，此时长为 a 的两条线段必处在三棱锥的对棱，不妨设 AD =BC =a ，BD =CD =AB =AC =2． 取 BC 中点 E ，连接 AE ，DE （见下图）．则 AE ⊥BC,DE ⊥BC ⇒BC ⊥平面AED ，V =13S △AED ⋅BC ， 在 △AED 中，AE =DE =√4−a 24，AD =a ，S △AED =12a √4−a 24−a 24=12a √4−a 22，所以 V =16a 2√4−a 22=16√a 2a 2(16−2a 2)⋅14，由均值不等式 a 2a 2(16−2a 2)≤(163)3，等号当且仅当 a 2=163时成立，即 a =43√3， 所以此时 V max =16√(163)3⋅14=1627√3．【知识点】棱锥的表面积与体积22. 【答案】(1) 由已知 a ⃗=2i ⃗+j ⃗，b ⃗⃗=mi ⃗+6j ⃗，且 a ⃗⋅b ⃗⃗=2m +6+(12+m )(i ⃗⋅j ⃗)=53m +2>0，得 m >−65；若 a ⃗ 和 b ⃗⃗ 同向，则存在正数 t ，使得 t (2i ⃗+j ⃗)=mi ⃗+6j ⃗， 由 i ⃗ 和 j ⃗ 不平行得，{2t =m t =6 得 m =12．故所求为 m >−65，m ≠12．(2) ①方程可变形为x−01=y−23，方向向量为 d⃗=(1,3)， 设法向量为 n ⃗⃗=(a,b )，由 n ⃗⃗⋅d ⃗=0 得 a +3b +12(3a +b )=52a +72b =0， 令 a =−7，b =−5，n ⃗⃗=(−7,5)；②取直线 l 上一点 B (0,2)，则 BA⃗⃗⃗⃗⃗⃗=(2,−1)，所求为 ∣∣BA ⃗⃗⃗⃗⃗⃗⋅n ⃗⃗∣∣∣n⃗⃗∣=∣√(⃗+5j ⃗)2=7√3926．【知识点】直线的点法向式方程（沪教版）、平面向量数量积的坐标运算。
