to solve the problems
It depends entirely on the problem. There are specific solutions to specific problems.
The answer depends on the precise nature of the problem.
he fiqued out the height of a pyramid using the length of its shadow and he was one of the first people to use geometry to solve practical problems.
Use the fact that the ratios of corresponding sides is the same, and also that corresponding angles have the same measure.

Descartes did not discover geometry - he invented analytical geometry, which enabled mathematicians to use algebra to solve problems in geometry and geometry to solve problems in algebra. The world would be less developed than now, as would be the case with most discoveries.
to develop your mentability on how you going to solve the problems
The answer depends on the precise nature of the problem.
you solve geometry by adding all the numbers and then divide it then you get the answer
idea
yes
It enabled geometric information to be converted into algebraic form. This meant that the tools of algebra could be applied to solve geometric problems and the tools of geometry to algebraic problems. That greatly increased the ability of mathematicians to solve problems.
The Cartesian system allows you to describe a geometric shape in algebraic terms. This allows algebraic techniques, such as differentiation or integration to be applied to solve problems in geometry. Conversely, geometrical results can be used to solve problems in algebra.
the scientific method :]
Not an answerable question. Geometry is an entire branch of mathematics with a huge range of applications. However, many individual problems etc in it can be described or solved by accurate drawing or by algebraic and numerical techniques.
