Education is the root to development. I personally believe that it is the solution of all the problems. All the wrong things occur in the society is due to lack of education. If people have knowledge , they can grow individually which together can form an educated and hence a developed nation.  As we know that every country developed through their people, it is the people from whom the country is. So, it is necessary for them to have knowledge about everything. If I get an opportunity with no restrictions over resources then I'll choose to educate the people of the country. In today's world of competition everyone wants to develop. For that it is necessary to give them knowledge about the things going around them.  So , I'll choose to help the people by providing enough facilities so that they can learn , can be independent and can take their own decisions.

What is a cyclic quadrilateral? A cyclic quadrilateral is a four-sided polygon whose all vertices lie on the circumference of a circle( i.e. inscribed in a circle). The radius and centre of this circle is circumradius and circumcentre respectively. The word cyclic comes from Ancient greek word ( kuklos) which means "circle" or "wheel". Properties of cyclic quadrilateral- 1. Opposite angles of a cyclic quadrilateral are supplementary which means that the sum of their opposite angles is equal to 180°. 2. If one side of a cyclic quadrilateral is produced, then the exterior angle so formed is equal to the opposite interior angle.

Basic Terms : Before discussing about formulas for finding area and circumference of circle , we need to study the following terms related to circle . 1. Area of circle  The area enclosed by a circle is known as area of circle. 2. Circumference of circle The perimeter i.e, the total length of the circle is known as it's circumference. 3. Radius A line drawn from centre of the circle to any point on it's circumference is known as it's radius.  In the above diagram, line segment OP drawn from the centre O to a point on circumference P is known as radius and is denoted by 'r'. Similarly, you can draw OQ, OR and OS as the radii of the given circle.  4. Diameter  In the above point we discussed about radius of circle. So, we can say that diameter is equal to double the radius of circle. Diameter is the line joining any two points on the circumference through the centre.  In the above diagram , PQ, RS, DE are the diamete...

Smallest Cell The smallest cell is the sperm cell.  The sperm is a male reproductive organ . The head of sperm cell measures about 4mm in length just slightly smaller than a red blood cell. Largest Cell The Ovum is the largest cell in human body. It is the reproductive cell in female body and it measures approximately 0.1 mm in diameter.

Smallest cell The smallest cell is Mycoplasma ( PPLO -  Pleuro pneumonia like organisms). It is about 10 micrometer in size.  Largest Cell The largest cell is the Ostrich's egg (Egg cell of Ostrich)  Ostrich Eggs are 6 inches (15cm) in diameter and can weight up to 1.3 kg. Longest Cell The nerve cell is the longest cell with a length of (90-100)cm.

Xylem Tissues Xylem tissues are responsible for transportation of water and minerals from roots to other parts of the plant.  Vascular plants are able to grow higher than other plants due to the rigidity of xylem tissues , which support the plant.  Components of Xylem Xylem vessels , Xylem parenchyma , Xylem fibres and Tracheids are the components of xylem. Phloem Tissues Phloem tissues are responsible for transportation of food prepared by the process of photosynthesis from leaves to other parts of the plant.  Other molecules such as proteins and mRNAs are also transported throughout the plant via phloem.

What is altitude in a triangle ? The altitude or height of a triangle is the line segment from a vertex that is perpendicular to the opposite side or base. Altitude of an equilateral triangle It is interesting to note that in an equilateral triangle , the altitude bisects the angle as well as the opposite side. Example - In the example above , a triangle is given which is an equilateral triamgle as all it's sides are equal (each 5cm). AD is the perpendicular drawn from vertex A to the base BC. Therefore, BD=BC and angle BAD is equal to angle CAD Because in an equilateral triangle , the altitude bisects the angle and the opposite side .
