NCERT Solutions Class 6 Maths Chapter 4 — Lines & Angles

Solution:

Step 1: A point is a fundamental concept in geometry. It represents an exact position or location in space.

Step 2: By definition, a point has no dimension; it has no length, width, or depth. It is often represented by a dot.

Solution:

Step 1: A line extends infinitely in both directions and has no endpoints.

Step 2: A line segment, on the other hand, is a part of a line that is bounded by two distinct endpoints. Its length can be measured.

Solution:

Step 1: A ray is a part of a line that has one endpoint and extends infinitely in one direction.

Step 2: It has a definite starting point but no definite end point.

Solution:

Step 1: A line is a straight path that extends infinitely in both directions and has no endpoints.

Step 2: A railway track extending infinitely in both directions perfectly fits the definition of a line.

Solution:

Step 1: Intersecting lines are lines that cross each other.

Step 2: By definition, two distinct lines can intersect at most at one single point. If they shared more than one common point, they would be the same line.
