सेवा में
प्रधानाचार्य,
केंद्रीय विद्यालय,
दिल्ली कैंट।
मान्यवर महोदय,
आपको विदित ही है कि हमारे विद्यालय में अनेक ऐसे विद्यार्थी हैं जो किसी न किसी रूप से शारीरिक विकलांगता से युक्त हैं। उन्हें विद्यालय में प्रथम अथवा द्वितीय तल पर स्थित कक्षाओं में जाने तथा प्रसाधन कक्षों का प्रयोग करने में बहुत कठिनाई होती है। आप से प्रार्थना है कि शारीरिक रूप से असमर्थ विद्यार्थियों की कक्षाएं निचले तल पर लगाई जाएं तथा सीढ़ियों के साथ-साथ रैंप भी बनाए जाएं जिससे उन्हें आने-जाने में तकलीफ न हो। उनके लिए पुस्तकालय, प्रसाधन कक्षों में भी समुचित व्यवस्था की जाए।
आशा है आप हमारी प्रार्थना को स्वीकार

R= {(L1, L2) : L1 is perpendicular to L2} Since no line can be perpendicular to itself ∴ R is not reflexive.
Let (L1, L2) ∈ R
∴ L1 is perpendicular to L2 ⇒ L2 is peipendicular to L1
⇒ (L2, L1) ∈ R
∴ (L1L2) ∈ R ⇒ (L2, L1) ∈ R
∴ R is symmetric
Again we know that if L1 is perpendicular to L2 and L2 is perpendicular to L3, then L1can never be perpendicular to L3.
∴ (L1, L2) ∈ R, (L2, L3) ∈ R does not imply (L1, L3) ∈ R
∴ R is not transitive.
