This notation, and much of the elementary theory of congruence, is due to the famous German mathematician, Carl Friedrich Gauss—certainly the outstanding mathematician of his time, and perhaps the greatest mathematician of all time.
Here is a wonderfully useful result. We break the proof into two parts: Congruence of integers shares many properties with equality; we list a few here. Parts 1, 2, 3 and 4 are clear by the definition of congruence. We'll prove parts 6 and 8, leaving parts 5 and 7 as exercises.
This follows from part 7, but it is easy to prove it directly: Be sure you notice how often we have used lemma 3. Here is a proof. It says that an integer and the sum of its digits are congruent modulo 9. In particular, one is congruent to 0 that is, divisible by 9 if and only if the other is.
Gauss — was an infant prodigy and arguably the greatest mathematician of all time if such rankings mean anything; certainly he would be in almost everyone's list of the top five mathematicians, as measured by talent, accomplishment and influence. Perhaps the most famous story about Gauss relates his triumph over busywork.

As Carl Boyer tells the story: When the instructor finally looked at the results, the slate of Gauss was the only one to have the correct answer,with no further calculation. Just short of his nineteenth birthday, he chose mathematics, when he succeeded in constructing under the ancient restriction to compass and straightedge a seventeen-sided regular polygon, the first polygon with a prime number of sides to be constructed in over years; previously, only the equilateral triangle and the regular pentagon had been constructed.
Gauss later proved precisely which regular polygons can be constructed. The answer is somewhat unsatisfying, however. Unfortunately, it is not known whether there are an infinite number of Fermat primes.
Gauss published relatively little of his work, but from to kept a small diary, just nineteen pages long and containing brief statements. This diary remained unknown until It establishes in large part the breadth of his genius and his priority in many discoveries.
When an important new development was announced by others, it frequently turned out that Gauss had had the idea earlier, but had permitted it to go unpublished.
He devoted much of his later life to astronomy and statistics, and made significant contributions in many other fields as well. His name is attached to many mathematical objects, methods and theorems; students of physics may know him best as the namesake of the standard unit of magnetic intensity, the gauss.Learn why the Common Core is important for your child.
What parents should know; Myths vs. facts. Although congruence statements are often used to compare triangles, they are also used for lines, circles and other polygons. For example, a congruence between two triangles, ABC and DEF, means that the three sides and the three angles of both triangles are congruent.
They can be at any orientation on the plane.
In the figure above, there are two congruent angles. Note they are pointing in different directions. If you drag any of the endpoints, the other angle will change to remain congruent with the one you are changing.
