William Dunham in Journey Through Genius attributes the first theorem, or equivalently a mathematical “truth with a proof “, to Thales of Miletus, and it gets called Thales Theorem.
What is the oldest theorem?
The oldest known proof
In this case of course the Pythagoras’ Theorem asserts that the ratio of the diagonal of a square to one of its sides is equal to the square root of 2.
What are the theorems in math?
Theorem, in mathematics and logic, a proposition or statement that is demonstrated . In geometry, a proposition is commonly considered as a problem (a construction to be effected) or a theorem (a statement to be proved).
What is theorem No 1?
Theorem 1: Equal chords of a circle subtend equal angles, at the centre of the circle . Converse of Theorem 1: If two angles subtended at the centre, by two chords are equal, then the chords are of equal length.
What is the first theorem in geometry?
The first such theorem is the side-angle-side (SAS) theorem : If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent. Following this, there are corresponding angle-side-angle (ASA) and side-side-side (SSS) theorems.
What are the 5 theorems?
In particular, he has been credited with proving the following five theorems: (1) a circle is bisected by any diameter; (2) the base angles of an isosceles triangle are equal; (3) the opposite (“vertical”) angles formed by the intersection of two lines are equal; (4) two triangles are congruent (of equal shape and size ...
What is axiom in math?
In mathematics or logic, an axiom is an unprovable rule or first principle accepted as true because it is self-evident or particularly useful . ... The term is often used interchangeably with postulate, though the latter term is sometimes reserved for mathematical applications (such as the postulates of Euclidean geometry).
Who is the father of mathematics?
Archimedes is considered the father of mathematics because of his notable inventions in mathematics and science. He was in the service of King Hiero II of Syracuse. At that time, he developed many inventions. Archimedes made out a pulley system designed to help the sailors move objects up and down that are weighty.
Who discovered zero?
History of Math and Zero in India
The first modern equivalent of numeral zero comes from a Hindu astronomer and mathematician Brahmagupta in 628. His symbol to depict the numeral was a dot underneath a number.
Who invented pi?
The Egyptians calculated the area of a circle by a formula that gave the approximate value of 3.1605 for π. The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.
What is a well known mathematical theorem?

How many types of theorems are there?
Theorems in the list which have not been formalized yet are in italics. Formalizations of constructive proofs are in italics too.
What is the two tangent theorem?
A line is tangent to a circle if and only if the line is perpendicular to the radius drawn to the point of tangency. The Two-Tangent Theorem states that if two tangent segments are drawn to one circle from the same external point, then they are congruent.
What are the 3 types of geometry?
In two dimensions there are 3 geometries: Euclidean, spherical, and hyperbolic . These are the only geometries possible for 2-dimensional objects, although a proof of this is beyond the scope of this book.
Why is it called Pythagorean Theorem?
The Pythagorean Theorem is named after Pythagoras of Samos , a mathematician who was also a religious leader , and believed that all things in the universe were composed of numbers. (There are many different ways to prove this.) The hypotenuse of a right triangle is the side opposite the right angle.
Is Pythagorean theorem only for right triangles?
The hypotenuse is the longest side and it’s always opposite the right angle. Pythagoras’ theorem only works for right-angled triangles , so you can use it to test whether a triangle has a right angle or not. In the triangle above, if.
