What Is The Meaning Of Geometry? | And History Of Geometry

What does geometry mean?

Geometry is one (1) of the oldest branches of mathematics. The word geo means 'earth' and matron means measure. So the word geometry means measure of the earth. Geometry is a branch of mathematics where we study the size, shape and relative position of statistics. The Greek mathematician Euclid is said to be the father of geometry.

What is geometry?

If you've ever wondered, 'What is geometry?', This wiki page is for you! Geometry is the part of mathematics that studies shape and space. It focuses on the formation of shapes and how they work in space. While learning geometry you will also learn about the shape, angle, dimensions and position of the object. In general, it is divided into two sides: plane geometry and solid geometry. They can also be called 2D and 3D geometry.

Plane geometry is flat, so a 2D square will be considered part of the plane geometry. 3D geometry is just as powerful as what we see and interact with in the world. A cuboid will be part of the solid geometry. At the end of the primary school curriculum, children should have a good understanding and knowledge about shapes and their characteristics.

What’s the history of geometry?

Geometry is much older and was studied thousands of years ago. The lessons and things that people learned about geometry then are still practiced and taught today. The earliest known evidence of geometry is found in Egypt, around 2000 BC. A set of rules about angles, areas, lengths and sizes was created that helped build buildings or build ships.

Then, the Greeks also began to study geometry. They used it to measure the size of the Egyptian pyramids and how far their ships were from the shore. Pythagoras was one of the most famous ancient Greek mathematicians. She was famous for his theories, and equations that are still used today. In 300 BC, a Greek named Euclid revolutionized everything he knew about geometry by developing mathematical proofs. The idea was that if you could prove something mathematically, it would have to be true.

Throughout history, different cultures have contributed to the study of geometry. Mathematics is always a way to bring together different communities and cultural people.

What are the concepts of geometry?

There are some concepts in geometry that are essential to know, especially if you want to move on to more advanced mathematics. Concepts can be divided into two types, plane geometry and solid geometry. Here is a list and some details of what each concept means:

Plane geometry

• Dimensions: There are four dimensions that we know that may sound strange because we are already in the third dimension. So, how can there be four (4)? This is because the first (1st) dimension has been classified as zero dimension. Imagine a dot on a piece of paper, it's zero dimension because it's just a dot of paper. Then, we move on to one dimensional line. From there you can connect four lines together and they form a square, which is two-dimensional. Turn that square into a cuboid and you're in the third dimension.
• Angles: There are six types of angles that can hold shape. These are right, rough, sharp, reflexive, full rotation and straight angles. All of this is used to measure how two lines meet inside a shape. For example, a square will have four right angles because all four angles must meet perfectly.
• Symmetry: Symmetry is when something stays the same on both sides. The most basic example of symmetry is the symmetry of reflection. The simplest reason to show this is that one half is equal to the other half. But, there are also rotating symmetries, which make your shape look the same when rotated.

Solid geometry

• Shapes: 3D geometry expresses mathematics in different shapes that cannot be shown on a 2D level. For example, it is impossible to draw on a piece of paper without the use of spheres and shadows. Taurus shape is a 3D donut shape.
• Volume: Volume is a 3D shape inside many parts of the house. How much can that 3D shape hold. Think of it as a jug filled with water, a jug that can hold water. It also shows a 3D size capability, how much it can hold before it overflows.
• Surface area: Surface area is important because it is the amount of space on a given surface in a 3D format. When you want to find the area on one side of a cube you can look with a cube. You are working the surface area on that side. When you try to figure out the surface area of ​​something that is not flat like a sphere or a cone, it becomes difficult and complex.
• Points, faces and edges: Another major part of solid geometry is the number of angles, faces and edges of the shape. These are important because they are accustomed to finding out the size and area.

What should you know?

Geometry skills are essential for a student to progress in other branches of mathematics like trigonometry and topology. This makes it important for all students to understand the basic principles of trigonometry.

From architecture to engineering, trigonometry is widely used in different common careers. Gaining an understanding of trigonometry opens a wide range of doors in the field of mathematics for students interested in continuing their study.

Conclusion

Geometry is the queen of science. Without the help of geometry we cannot make any predictions in science. Geometry perfects science. So we should learn and understand geometry with great pleasure.

Frequently Asked Questions (FAQ)

What does point mean in geometry?
Consider a pair of real numbers. Call each such pair a "point". Given two such points (a, b) and (c, d), define the line defined by (a, b) and (c, d) so that all the points of the form contain (ta + (1-t) c, tb + (1 – t) d) where t is a real number.

What does t mean in geometry?

• Parallel lines are lines that never cross or intersect.
• But the perpendicular lines intersect at a right angle.
• The symbol for 2 parallel lines is 2 vertical lines (e.g. ||)
• Where the symbol of 2 perpendicular lines is a reciprocal of an inverted-down ⊥ or T.

What is the difference between math and geometry?
There is a narrow view of geometry where it is a branch of mathematics, and there is a broad view of geometry that it is a method of almost any type of mathematics.

What are examples of geometry terms?
Lines, circles, parabolas, hyperbolas, curves, ellipses, dots, ovals, differential and analytical manifolds, affine, variations, coordinates, conjectures, surfaces.

How is geometry used?

Mathematics, physics, chemistry, geology, biology… poetry, linguistics… and anything that might pop up in anyone's mind… geometry everywhere!

In Fact, All Over The Place!

What can be done with geometry?
Engineering, fixing things, science, manufacturing, anything related to the real world works with geometry and many like science and technology rely on it.
