Answers
Answer:
कोणत्याही दिलेल्या एका बिंदुतून किती रेषा जाऊ शकतात?
Answer:
1. Infinite
2. One line
3. One
4. Yes
5. No
6. A point or a line.
7. A line.
Step-by-step explanation:
1. Infinite number of straight lines can pass through a single point.
2. Only one single line can pass through the two given points and is known as a line segment.
3. A line with one point fixed and the other point containing an arrow is known as Ray.
4. Yes, three points can be identical and they are known as Collinear points as they lie on the same straight line.
5. No, If two lines intersect each other then they are known as Intersecting points whereas two lines are known as parallel lines if they never intersect. So, parallel and intersecting lines are totally opposite concepts.
6. Intersection of a plane and a line will either be a single point or a line if the line lies in the plane.
7. When two planes intersect each other, it forms a line. As planes are infinite, so they cannot intersect at a single point and also as planes are flat, so they cannot intersect over more than a single line.
