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°

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.

Hitler was a powerful orator. His speech could mesmerise the masses. The factors responsible for the meteoric rise of Hitler are (i) He promised to build a strong nation, undo the injustice of the Versailles Treaty and restore the dignity of the German people. (ii) He assured employment for unemployed people and a secured future for the youths. (iii) He promised to control all foreign influence and resist all foreign conspiracies against Germany. (iv) He introduced a new style of politics. Nazi party held massive rallies and public meetings to demonstrate the support for Hitler and this massive mobilisation created a sense of unity among German people. (v) Nazi propaganda skilfully projected Hitler as a messiah, a saviour as someone who had arrived to save people from their distress. (vi) Hitler came during such a period when the dignity and pride of German people were totally shattered due to the defeat in the First World War and humiliating Treaty of Versailles. The crisis in the economy, polity and society formed the background of Hitler's rise to power.
