Philosopher lived in Ancient Greece now forms a part of Turkey.

Thales regarded as the

Thales used geometry to calculate the distance
of a ship from the shore. He also figured out a way to measure the height of a
Pyramids.**First True Mathematician**, because of the many important contributions made to the field of Mathematics, Especially in Geometry.
Its a very interesting way. The time
of day when his own shadow was same height that he was he measure the shadow of
the Pyramid to get the height.

Thales was a great mathematician, He
proves that:--

- A circle is bisected or cut into halves by its
diameter.
- The angle at the base of an isosceles triangle are
equal.
- An angle is is the shape of the space between two
straight lines at the point where they meet.
- If two straight line cut one another, the opposite
angles are equal. Now known as Vertically opposite angle.
- If two triangles have two angle and a side in common,
the triangles are identical. Now known as AAS (Angle Angle Side) Law.

Wao great
