Question
A prism is a 3-D figure obtained by moving the base (which is a plane) of the prism along a straight line. The base of a certain prism is cornered at 5 places, with each corner forming a certain angle. This prism is called a pentagonal prism, “penta” because it has 5 angles.
As you know that two lines are required to form an angle, we would require 10 lines to construct the base of this prism (2 lines each for one angle). Say True or False.

Solution
The correct option is B False
Both the lines, which form an angle in a closed figure, are also involved in the formation of one other angle, so that the total number of lines required to form a pentagon is five.
False
Both the lines, which form an angle in a closed figure, are also involved in the formation of one other angle, so that the total number of lines required to form a pentagon is five.
