Minutes in Geometry

There are several ways to measure the size of an angle. One way is to use units of degrees. (Radian measure is another way.) In a complete circle there are three hundred and sixty degrees.

An angle could have a measurement of 35.75 degrees. That is, the size of the angle in this case would be thirty-five full degrees plus seventy-five hundredths, or three fourths, of an additional degree. Notice that here we are expressing the measurement as a decimal number. Using decimal numbers like this one can express angles to any precision - to hundredths of a degree, to thousandths of a degree, and so on.

There is another way to state the size of an angle, one that subdivides a degree using a system different than the decimal number example given above. The degree is divided into sixty parts called minutes. These minutes are further divided into sixty parts called seconds. The words minute and second used in this context have no immediate connection to how those words are usually used as amounts of time.


Symbols used


In a full circle there are 360 degrees. Each degree is split up into 60 parts, each part being 1/60 of a degree.  These parts are called minutes. Each minute is split up into 60 parts, each part being 1/60 of a minute. These parts are called seconds.

There are symbols that are used when stating angles using degrees, minutes, and seconds. Those symbols are show in the following table.
Symbol for degree:  º
Symbol for minute:   '
Symbol for second:  "

Understanding equation for square root is always challenging for me but thanks to all math help websites to help me out.

Example


So, the angle of 40 degrees, 20 minutes, 50 seconds is usually written this way:

How could you state the above as an angle using common decimal notation? The angle would be this many degrees, (* means times.):
40 + (20 * 1/60) + (50 * 1/60 * 1/60)

That is, we have 40 full degrees, 20 minutes - each 1/60 of a degree, and 50 seconds - each 1/60 of 1/60 of a degree.

Work that out and you will get a decimal number of degrees.  It's 40.34722 º

Geometry in Our World

Introduction to geometry in our world

Geometry is one of those subjects that make students wonder when they will ever use it again. Yet, it has many applications in daily life in our world.


Geometry is especially useful in home building or improvement projects. If you want to find the floor area of a house, you use geometry. This information is useful for laying carpet or tiles and for telling an estate agent how big your house is when you want to put it on the market. If you want to reupholster a piece of furniture, you have to estimate the amount of fabric you need by calculating the surface area of the furniture.

Applications of geometry in our world


Geometry also has applications in our world in hobbies.  The water in a goldfish tank needs to have a certain volume as well as surface area in order for the fish to thrive. You can calculate it using geometry. Pastimes like quilting and other design projects use geometry extensively. Understanding how the shapes of a quilt block fit together is dependent on geometry; so is determining the amount of fabric you need.

Geometry in daily life in our world


Geometry plays an important role in every day life. For example, geometry is used in the planning and making of buildings, roads, bridges and houses. Geometrical tools are utilized in making maps and it aids a lot in exploring distances. Geometry is mostly used in drawings, sewing,mathematics,architecture, measurements and so on. It is also used in space, engineering, fashion designing etc.

One  biggest use of geometry is for coordinate transformation (rectangular to polar or vice versa). Many of the applications  you mention make more use of rules of thumb and/or formulas or tables that have been worked out on the basis of geometry. The underlying geometry may be used only rarely.

USE OF GEOMETRY IN DAILY LIFE

Geometry is the one of the subject that make students wonder when they will ever use it again .yet; it has many applications in daily life.

Geometry is especially used in home building or improvement projects .if you want to find the floor area of a house, you can use geometry. These information is useful for telling an estate , how big your house is when you want to put it on the market .if you want to purchase a piece of wood ,you have to estimate the amount of varshines you need the calculating the surface area of the wood.


Importance of study of geometry


Geometry is considered the important field of study, because it has many applications in daily life .for example, a sport car move in a circular path and it applies the concepts of geometry. Stairs are made in the homes in consideration to angle of geometer and stairs and designed to 90 degree. When you throw a round ball in a round basket ball, it is also an application of geometry .Moreover, geometry is widely used the field of many ways such as architecture, decorators, engineers etc. In the architecture for building design and map marking, in addition, geometrical shapes are circle, rectangle, polygon, square, are used in the artists. The most interesting example is the nature of speaks of geometry and you can shapes in all things or nature.

I have recently faced lot of problem while learning difference of two squares formula, But thank to online resources of math which helped me to learn myself easily on net.

In daily life there is a lot of use of geometry by Architects, Decorates,

Engineers and many other professionals in determining distances, volume, angles , areas etc and it helps in understanding the proportion of thing in the universe. There is a wide use of geometry in textile and fashion designing and countless other areas.

Geometry is used because we need to help us the house hold tasks like putting carpet in the room ,if you need to know that the shape of the room is and then you need to know the area formula for that the shape so therefore it  is used in the way.

Geometry is at work everywhere you go. Without geometry, we would not be able to build things, manufacture things or play sports with must success. Geometry not only makes in every day life possible, it makes them easier by providing us with an exact science to calculate measurement of shape.
