2.  Born in unknown (mid-4th century
BC)
 Died in unknown (mid-3rd century BC)
 Residence in Alexandria, Egypt.
 Fields in Mathematics.
 Known for Euclidean geometry
Euclid's Elements.

3.  Euclid also known as Euclid of Alexandria,
was a Greek mathematician, often referred
to as the "Father of Geometry".
 He was active in Alexandria during the
reign of Ptolemy I (323–283 BC).
 His Elements is one of the most influential
works in the history of mathematics, serving
as the main textbook for
teaching mathematics from the time of its
publication until the late 19th or early 20th
century

4.  In the Elements, Euclid deduced the
principles of what is now
called Euclidean geometry from a small
set of axioms.
 Euclid also wrote works
on perspective, conic sections ,spherical
geometry, number theory and rigor.

5.  A point is that which has no part.
 A line is a breadthless length.
 The extremities of lines are points.
 A straight line lies equally with respect to
the points on itself.
 A surface is that which has length and
breadth only.

6.  Edges of surface are lines.
 A plane surface is a surface which lies
evenly with the straight lines

7.  Things which are equal to the same thing
are equal to one another.
 If equal are added to equals, the whole
are equal.
 If equal are subtracted to equals, the
remainder are equal.
 Things which coincide with one another
are equal to one another.

8.  The whole is grater than a part.
 Things which are double of the
same things are equal to one
another.
 Things which are halves of the
same things are equal to one
another.
