Four Geometry Formulas

When you start a geometric course, students are often familiar with the official that is commonly used in mathematics. These equations include finding the perimeter and area of ​​a two-dimensional graph, and finding the volume and surface area of ​​a three-dimensional graph. For each different shape, there are related equations to find its surrounding, area, volume or surface area. Therefore, we focus only on the four special form or four formulas of numbers. You can see the perimeter of the square, the area of ​​the triangle, the volume of the right cylinder, and the total surface area of ​​the sphere.

Geometry is very important. I personally think that it is very easy. For geometry, first move to triangle, square, polygon, circle, coordinate. Again, please do not look into mathematics too much and start to solve it. Finally, please introduce 3D geometry. Measure problem and regional problem by angle. If you have 20 days of preparation, I recommend you give to you 2-3 hours a day. In the first week of 20 days, you have to complete all the topics I mentioned above. You should do this without mercy. We strongly recommend that you carry out diagnostic tests before you start preparing. We have a lot. I will give some links to some of them later.

My geometric teacher is wrong person teaching me geometry. I read the documentary on bees and after finishing the book about zero, I noticed that everything in this world is geometric. For example, the first mathematician did not have numbers or formulas. They have measurements, quantity and shape of things ... They have geometry, not mathematics. Ancient bees also use geometry. Today, we do not have geometry at school, we just have numbers. Bees are geniuses, they are not lazy. In fact, they are very smart. They know that food and shelter are necessary to survive. For this purpose, they are raising their houses, and hives ranged for thousands of years. This sounds normal, but if you check the honeycomb, you will see an interesting and attractive part of a hexagonal cell. Yes, the bees have complete design capabilities to produce and store honey with a geometrically shaped hexagonal wax comb.

It rarely stops thinking about the interaction between arithmetic and geometry. When asked to sum the first 100 odd - odd integers, we quote a narrow calculation, perhaps even an expression. We do not draw those numbers and stop looking at their shape and symmetry. When we combine geometry and numbers with a bold leap, our courage will discover new and unexpected patterns that transform awkward quantities into beauty. Students retreat from algebra as if they fell from Martian; who can blame them? Algebraic learning is isolated, algebraic is ugly and confusing at all. But when we reveal its abstract veil and tie the algebra to its close relatives and adjust the geometry, we reach a new level of understanding. The idea of ​​using two numbers to represent each point on the plane (the x and y coordinates currently known) is a nod to Cartesian creativity.
