Ventilators are machines that blow air—or air with extra oxygen—into your airways and your lungs. Your airways are pipes that carry oxygen-rich air to your lungs when you breathe in. They also carry carbon dioxide (a waste gas) out of your lungs when you breathe out.

Karamjali is one of the favorite swear words that come to one's mind when you think of old movies with a lot of domestic verbal violence, and most of the times, Lalita Pawar there. :) Karamjala, or Karamjale, or Karamjali, is made of two parts, Karam, that is 'karm', meaning works, deeds, and Jalna, to burn

GIVEN: In ∆ABC & ∆PQR, D & S are the mid points of the sides BC & QR . ΔABC ~ ΔPQR AB/PQ = BC/QR = AC/PR ………...(i) [corresponding sides of two similar triangles are in proportional] Also, ∠A = ∠P, ∠B = ∠Q, ∠C = ∠R …...…(ii) [corresponding angles of two similar triangles are in equal] BD = CD = 1/2 BC and QS = SR = 1/2QR…….…...(iii) [D is the midpoint of BC and S is the midpoint of QR] AB/PQ = BC/QR [From eq (i)] AB/PQ = 2BD/2QS [From eq iii ] AB/PQ = BD/QS……………(iv) In ΔABD and ΔPQS, ∠B = ∠Q [From eq (ii)] AB/PQ = BD/QS [From eq (iv)] ΔABD ~ ΔPQS (By SAS similarity criterion) AB/PQ = AD/PS [corresponding sides of similar triangles are proportional] Hence, proved.

in triangle ABC, sides are 'a' units as AD is perpendicular to BC , then in triangle ABD , AB2 = AD2 + BD2 a2 = AD2 + (a/2)2 [ since AD is perpendicular to BC ] a2 - a2/4 =AD2 = 3a2 /4 = AD2 ..........(1) in triangle ADC, AC2 = AD2 + CD2 a2 = AD2 + (a/4)2 3a2/4 = AD2 .........(2) from equation 1 and 2 3 a2 /4 = AD2 3 a2 = 4 AD2 3 AB2 = 4AD2 [since AB = a ]
