Mark three points on a piece of paper in such a way that they are not in a ling
Join them taking two points at a time. How many line segments have you
drawn? What figure have you got?
Answers
Step-by-step explanation:
In Fig. 10.33, name:
(i) Five line segments.
(ii) Five rays.
(iii) Non-intersecting line segments.
ANSWER:
(i) Five line segments are PQ, RS, PR, QS and AP.
(ii) Five rays are −→QC,−→SD,−→PA,−→RB and −→RA.
(iii) Non-intersecting line segments are PR and QS.

Question 3:
In each of the following cases, state whether you can draw line segments on the given surfaces:
(i) The face of a cuboid.
(ii) The surface of an egg or apple.
(iii) The curved surface of a cylinder.
(iv) The curved surface of a cone.
(v) The base of a cone.
ANSWER:
(i) Yes, we can draw line segments on the face of a cuboid.
(ii) No, we cannot draw a line segment on the surface of an egg or apple.
(iii) Yes, we can draw line segments on the curved surface of a cylinder.
Every line segment parallel to the axis of a cylinder on the curved surface will be a line segment.
(iv) Yes, we can draw line segments on the curved surface of a cone.
Every line segment joining the vertex of a cone and any point on the circumference of the cone will be a line segment.
(v) Yes, we can draw line segments on the base of a cone.
