The five tools that enabled the Greeks to utilize the five basic postulates of Euclidean geometry are the straightedge, compass, ruler, protractor, and a set square. The straightedge was used for drawing straight lines, while the compass allowed for the construction of circles and arcs. The ruler helped measure lengths, and the protractor was essential for measuring angles. The set square facilitated the construction of right angles and parallel lines, supporting the geometric principles established by Euclid.
Among the five basic postulates of Euclidean geometry, the first states that a straight line can be drawn between any two points. The second postulate asserts that a finite straight line can be extended indefinitely in both directions. The third postulate specifies that a circle can be drawn with any center and radius. Lastly, the fifth postulate, often called the parallel postulate, states that if a line intersects two other lines and forms two interior angles on the same side that are less than two right angles, the two lines will eventually meet on that side when extended.
Geometry, unlike science, doesn't really have laws, it has theorems, and many different mathematicians contributed to the creation of the basic theorems of geometry. Perhaps the best known is Pythagoras.

Starting from around 3rd-4th grade, you start to learn really basic geometry. But around 8th or 9th grade, you actually start to learn more advanced geometry that uses theorems and postulates and proofs.

The basic constructions required by Euclid's postulates include drawing a straight line between two points, extending a line indefinitely in a straight line, drawing a circle with a given center and radius, constructing a perpendicular bisector of a line segment, and constructing an angle bisector. These constructions are foundational in Euclidean geometry and form the basis for further geometric reasoning.

Yes, you can move from basic Algebra to Geometry, but only upon recommendation from your teacher.

The answer depends on what the requirements for the basic construction are.
