Lines which lie in the same plane but do not intersect are said to be ____ to each other.

An arrow head is drawn at one end of the ray to show that it is _____ on that side.

A line segment has two points showing its limits. They are called_____

______ is used to name a point.

Name the different line segments and rays in the given figure:

Look at the figure alongside and answer the questions given below:
i. Name the parallel lines.
ii. Name the concurrent lines and the point of concurrence.
iii. Write the different names of line PV.

Determine the collinear and non-collinear points in the figure alongside:

Take a flat piece of thermocol or cardboard, a needle and thread. Tie a big knot or button or bead at one end of the thread. Thread the needle with the other end. Pass the needle up through any convenient point P. Pull the thread up, leaving the knot or the button below. Remove the needle and put it aside. Now hold the free end of the thread and gently pull it straight. Which figure do you see? Now, holding the thread straight, turn it in different directions. See how a countless number of lines can pass through a single point

There are 9 points in the figure. Name them. (Textbook pg. no. 3)
i. If you choose any two points, how many lines can pass through the pair?
ii. Which three or more of these nine points lie on a straight line?
iii. Of these nine points, name any three or more points which do not lie on the same line.

Write the different names of the line.

Observe the given figure. Name the parallel lines, the concurrent lines and the points of concurrence in the figure.

Look at the figure alongside and name the following:


i. Collinear points
ii. Rays
iii. Line segments
iv. Lines
