What is geometry?
The word geometry derives from the Ancient Greek geo (earth) and metron (measurement). “Earth – measure” is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space. Geometry is one of the oldest mathematical sciences.
Where is geometry?
Geometry is everywhere. Everywhere in the world you see geometry .It is happening in the world all around us. It is found in art, architecture, engineering, robotics, land surveys, astronomy, sculptures, space, nature, sports, machines, cars and much more. Geometry is used and found everywhere in the world in some way or the other. Man-made structures that include geometric structures would be almost everything. If a person looks closely, they would see geometry in the structure. Nature even has its own geometric structures. The world is a big sphere, so is the moon and the other 8 planets in the Solar System. The whole Universe is a geometric structure, which proves that not only man-made structures are geometric but that even nature has geometry. Geometry exists even in things a human cannot see, just know it’s there.
Geometry in buildings and structures
All the structures in the world are geometric.
This is a structure with basic geometric shapes found everywhere. This is a modern reconstruction of the English Wigwam. As you can see there the door way is a rectangle, and the wooden panels on the side of the house are made up of planes and lines. Except for really planes can go on forever. The panels are also shaped in the shape of squares. The house itself is half a cylinder.
This is a modern day skyscraper at MIT. The openings and windows are all made up of parallelograms. Much of them are rectangles and squares. This is a parallelogram kind of building.
This is the Pyramids, in Indianapolis. The pyramids are made up of pyramids, of course, and squares. There are also many 3D geometric shapes in these pyramids. The building itself is made up of a pyramid, the windows a made up of tinted squares, and the borders of the outside walls and windows are made up of 3D geometric shapes.
This is the Hancock Tower, in Chicago. With this image, we can show you more 3D shapes. As you can see the tower is formed by a large cube. The windows are parallelogram. The other structure is made up of a cone. There is a point at the top where all the sides meet, and There is a base for it also which makes it a cone.
This is a Chevrolet SSR Roadster Pickup. This car is built with geometry. The wheels and lights are circles, the doors are rectangular prisms, the main area for a person to drive and sit in it a half a sphere with the sides chopped off which makes it 1/4 of a sphere. If a person would look very closely the person would see a lot more shapes in the car.
These were all basic geometry shapes in the world today. There are a lot more structure and things that contain geometry but that would be too many to list.
The golden rectangle
A golden rectangle is one whose side lengths are in the golden ratio, or approximately 1:1.618o34.
A golden rectangle with longer side a and shorter side b, when placed adjacent to a square with...
