【推荐1】给出下列三个命题:
①若直线eqId417e80f1349244878d01fe90e0891f5f与平面eqIdc13953f2514e4c8f9c8aaaf5241c33ac平行,则eqId417e80f1349244878d01fe90e0891f5f与平面eqIdc13953f2514e4c8f9c8aaaf5241c33ac内的任意一条直线都没有公共点;
②若直线eqId417e80f1349244878d01fe90e0891f5f与平面eqIdc13953f2514e4c8f9c8aaaf5241c33ac所成角为eqIdb9383ae687874bf9a7a4a81aefe24376,则经过eqId417e80f1349244878d01fe90e0891f5f有且只有一个平面与eqIdc13953f2514e4c8f9c8aaaf5241c33ac垂直;
