Geometry is the part of mathematics that studies the size, shapes, positions and dimensions of things. ... Squares, circles and triangles are some of the simplest shapes in flat geometry. Cubes, cylinders, cones and spheres are simple shapes in solid geometry. The definition of geometry is a branch of math that focuses on the measurement and relationship of lines, angles, surfaces, solids and points. An example of geometry is the calculation of a triangle's angles. Geometry helps us in deciding what materials to use, what design to make and also plays a vital role in the construction process itself. Different houses and buildings are built in different geometric shapes to give a new look as well as to provide proper ventilation inside the house.

Any peripheral device that is not housed inside the computer cabinet. Monitors, keyboards, mice and printers are inherently external devices; however, drives, network adapters and modems may also be external. See external drive, external modem and USB adapter. There are two main types of external hard drives, portable and desktop. Primary External Storage is one that is accessible by the user but still part of the built-in memory. That's where you store your photos, documents, and other data even though when you don't have an SD card installed. In short, your phone's built-in memory is divided into two parts.

The dictionary definition of migratory bird is a bird that travels from one place to another at regular times often over long distances. Most native bird species (birds naturally occurring in the United States) belong to a protected family and are therefore protected by the Migratory Bird Treaty Act. Birds migrate to move from areas of low or decreasing resources to areas of high or increasing resources. The two primary resources being sought are food and nesting locations. At least 4,000 species of bird are regular migrants. That's about 40 per cent of the world's total. But some parts of the world have a higher proportion of migrants than others. In far northern regions, such as Canada or Scandinavia, most species migrate south to escape winter.

Let positive integer a = 4m + r , By division algorithm we know here 0 ≤ r < 4 , So
When r = 0
a = 4m 
Squaring both side , we get
a² = ( 4m )²
a² = 4 ( 4m​²)
a² = 4 q , where q = 4m²

When r = 1
a = 4m + 1
squaring both side , we get
a² = ( 4m + 1)²
a² = 16m² + 1 + 8m 
a² = 4 ( 4m² + 2m ) + 1 
a² = 4q + 1 , where q = 4m² + 2m

When r = 2
a = 4m + 2 
Squaring both hand side , we get
a² = ​( 4m + 2 )²
a² = 16m² + 4 + 16m 
a² = 4 ( 4m² + 4m + 1 )
a² = 4q , Where q = ​ 4m² + 4m + 1

When r = 3 
a = 4m + 3
Squaring both hand side , we get
a² = ​( 4m + 3)²
a² = 16m² + 9 + 24m 
a² = 16m² + 24m ​ + 8 + 1
a² = 4 ( 4m² + 6m + 2) + 1
a² = 4q + 1 , where q = 4m² + 6m + 2 
Hence 
Square of any positive integer is in form of 4q or 4q + 1 , where q is any integer.

A sense of pride is the feeling of deep pleasure or satisfaction which comes from your achievements. Taking pride in your work is a massively important role for any professional. ... The fact that seafarers make the world work, should be a source of immense pride and satisfaction.

Root words help us figure out the origin and meaning of the language we use today. In the same way, knowing our "roots" help us figure out our origins and our purpose. We all come from somewhere, and we all mean something; because of our strong roots, we can become great trees (figuratively). A family tree is a chart that maps lineage, usually of a particular person, as far back as records allow. A family tree often begins with the current generation and works backwards. A family tree can also mean starting with the oldest known generation and working forwards.

A noun is a word that names a person, place, thing, or idea. Concrete nouns name people, places, or things that you can touch, see, hear, smell, or taste. These nouns are intangible, which means you cannot touch, see, hear, smell, or taste them using your five senses. Nouns come in a lot of different shapes and sizes. The major ones are common nouns, proper nouns, abstract nouns, possessive nouns, and collective nouns.
