Thales is credited with having discovered the following mathematical phenomena:
- A circle is bisected by any diameter.
- The base angles of an isosceles triangle are equal.
- The angles between two intersecting straight lines are equal.
- Two triangles are congruent if they have two angles and one side equal.
- An angle in a semicircle is a right angle.
Thales was one of the first to prove his concepts by logical reasoning and to look at geometrical figures as abstractions. These two approaches were a step forward from previous mathematics.
