Question

11.If l, m and n are three lines such that l || m and m || n, prove that l || n.

Answer 1

Step-by-step explanation:

Given! || , m,n perpendicular |

To prove: n Im

Since I || m and n intersects them at G

and H respectively

::Z1= Z2 [Corresponding angles]

But, U = 90° [n 1]]

→ Z2 = 90°

Hence n perpendicular m
