MidPoint Theorem Statement
The midpoint theorem states that “The line segment in a triangle joining the midpoint of two sides of the triangle is said to be parallel to its third side and is also half of the length of the third side.”
Construction- Extend the line segment DE and produce it to F such that, EF=DE.
In the triangle, ADE, and also the triangle CFE
EC= AE —– (given)
∠CEF = ∠AED {vertically opposite angles}
EF = DE { by construction}
hence,
△ CFE ≅ △ ADE {by SAS}
Therefore,
∠CFE = ∠ADE {by c.p.c.t.}
∠FCE= ∠DAE {by c.p.c.t.}
and CF = AD {by c.p.c.t.}
The angles, ∠CFE and ∠ADE are the alternate interior angles. Assume CF and AB as two lines which are intersected by the transversal DF.
In a similar way, ∠FCE and ∠DAE are alternate interior angles. Assume CF and AB are the two lines which are intersected by the transversal AC.
Therefore, CF ∥ AB
So, CF ∥ BD
and CF = BD {since BD = AD, it is proved that CF = AD}
Thus, BDFC forms a parallelogram.
By the use of properties of a parallelogram, we can write
BC ∥ DF
and BC = DF
BC ∥ DE
and DE = (1/2 * BC).
Hence, the midpoint theorem is Proved.

In September 1939, Germany invaded Poland with the result that it started a war with France and England. In September 1940, Tripartite Pact with Italy and Japan and Germany was signed. By the end of 1940, Hitler had almost won all the wars. Hitler attacked the Soviet Union in June 1941. The Soviet Red Army gave a crushing defeat to the German soldiers. In the meantime, the US also entered the war when the Japanese bombed the US base at Pearl Harbor. The war ended in May 1945, with Hitler’s defeat and US dropping of atom bomb on Hiroshima in Japan.

Cold water exerts more pressure than warm air as cold air is denser than warm air while warm air is lighter and less denser than warm air so less pressure is exerted.

Hot air is lighter than atmospheric air.
The air inside the hot air balloon is less dense.
It causes the hot air balloon to rise as it is lighter than surrounding air.

When air rushes over the curved upper wing surface, it has to travel further than the air that passes underneath, so it has to go faster (to cover more distance in the same time). According to a principle of aerodynamics called Bernoulli's law, fast-moving air is at lower pressure than slow-moving air, so the pressure above the wing is lower than the pressure below, and this creates the lift that powers the plane upward.

Unemployment is defined as to exist that peoples who are willing to do work at the going wages can't find jobs.
The 3 main categories of unemployment are
1. Structural unemployment: This kind of unemployment happens when the demand for a special type of worker is not available. This happens due to the difference between the skills an employer is taking for, and the skills workers actually have.
2. Frictional unemployment: This kind of unemployment arises when workers left their job and search for another one. The time gap between this mentioned as frictional unemployment. Example – quitting or termination.
3. Cyclical unemployment: This kind of unemployment appears when there is a regress and many people lose their posts. When the economy goes up and down, based on these cycles, people became unemployed. That is why this is called cyclical unemployment.
