Sahara is the world’s largest desert. Yet beneath its surface could be found vast aquifers of fresh water. The basis of the huge ‘buried treasure’ of water was laid down in prehistoric times. The water found is clean and refreshing. 6000 years ago, Sahara was quite a different place. It was full of greenery and water. Prehistoric rock-art of Sahara indicates the presence of hippopotamuses which need water round the year. Migration of Paleo-monsoon to the Sahara region led to its wet and rainy climatic conditions. Later, around 5000 years ago, the monsoon shifted towards south, leaving Sahara in a state of drought. This led the inhabitants to migrate to the Nile Valley. The shift in the earth’s axis and decreased precipitation left the place dried out. Consequently, the soil lost its ability to hold water and vegetation decreased. For the past 4000 years Sahara has remained the same.

अँधेर नगरी प्रसिद्ध हिंदी साहित्यकार भारतेंदु हरिश्चंद्र का सर्वाधिक लोकप्रिय नाटक है। ६अंकों के इस नाटक में विवेकहीन और निरंकुश शासन व्यवस्था पर करारा व्यंग्य करते हुए उसे अपने ही कर्मों द्वारा नष्ट होते दिखाया गया है। भारतेंदु ने इसकी रचना बनारस के हिंदू नेशनल थियेटर के लिए एक ही दिन में की थी।

Advantage of word processor over typewriter are- when we make a mistake in typewriter we have to type the whole document again while in word processor we can make the mistake correct- to send the document to different address we have to write the document separately for each address and in word processor we have to write it once and can be sent to many addresses

Let a square ABCD in which L, M, N & O are the midpoints.
In {tex}\triangle{/tex}AML and {tex}\triangle{/tex}CNO
AM = CO (AB = DC and M and O are the midpoints)
AL = CN (AD = BC and L and N are the midpoints)
{tex}\angle{/tex} MAL = {tex}\angle{/tex}NCO (all angles of a square = 90°)
by AAS criteria
{tex}\triangle{/tex}AML {tex}\cong{/tex} {tex}\triangle{/tex}CNO
{tex}\therefore{/tex} ML = ON (CPCT)
similarly {tex}\triangle{/tex}MBN {tex}\cong{/tex} {tex}\triangle{/tex}LDO
now,
in {tex}\triangle{/tex}AML,
{tex}\angle{/tex}AML = {tex}\angle{/tex}ALM (AM = AL)
= 45°
similarly in {tex}\triangle{/tex}LDO
{tex}\angle{/tex}DLO = 45°
{tex}\therefore{/tex} {tex}\angle{/tex} MLO = 90°
by the properties of SQUARE
All sides are equal and angles are 90°
