Question

1.Two planes intersect each other to form a) plane b) point c)straight line d)angle

2. Which of the following is an example of a geometrical line a) black board b) sheet of paper c) meeting place of two walls d) ship of sharp pencil

Answer 1

Answer:

1) Option (c) is correct

2) Option (c) is correct

Step-by-step explanation:

1.Two planes intersect each other to form a straight line.
