Question

if L,M,N are three lines such that L||M and n L prove that n m​

Answer 1

Answer:

Noble gases are present to the extreme right in the periodic table and they have stable configuration with complete octet so they have highest ionization potential for loss or gain of electron.

Answer 2

Answer:

Given l || m, n perpendicular l

To prove: n ⊥ m

Since l || m and n intersects them at G and H respectively

∠1 = ∠2 [Corresponding angles]

But, U = 90o [n ⊥ l]

∠2 = 90o

Hence n perpendicular m
