Multiple-choice question: This big question is ***7 small questions, with 5 points for each small question, out of 35 points; Of the four options given in each question, only one meets the requirements of the topic.
1, it is known that the straight line of the sum of crossing points is parallel to the straight line, so the value of is (a).
A.B. C. D。
2. The equation of the straight line passing through the point and perpendicular to the straight line is (b)
A.B.
C.D.
3. The following four conclusions:
(1) Two different straight lines are parallel to the same plane, so the two straight lines are parallel.
⑵ Two different straight lines are parallel if there is no common point.
(3) If two different straight lines are perpendicular to the third straight line, then the two straight lines are parallel.
(4) A straight line has nothing in common with countless straight lines in the plane, so the straight line is parallel to the plane.
The correct number is (a)
A.B. C. D。
