Kushagra is drawing a railway track on paper as a part of his project. He asked Sarosh to draw a line parallel to the given line. Sarosh said that we can only construct a line parallel to the given line using alternate angles concept. Is this true?
False
We can construct a line parallel to a given line by using alternate angles as well as corresponding angles concept. So, the statement is false.
If two parallel lines are intersected by a transversal:
(i) alternate interior angles are equal i.e., 2=8 and 3=5
(ii) alternate exterior angles are equal i.e., 1=7 and 4=6
(iii) corresponding angles are equal i.e., 1=5,4=8,2=6 and 3=7
(iv) co-interior angles are supplementary i.e., 2+5=180∘ and 3+8=180∘
A line can be constructed parallel to a given line by making any of the above mentioned pairs of angles equal.
