Euclid developed Euclidean geometry around 300 BC. I cannot get much briefer than that.
Geometry is the study of all shapes. This includes octagons. Trigonometry developed much later than geometry for applying the study of triangles to practical application.
René Descartes developed analytic geometry
They developed several kinds of mathematics, Astronomy, and geometry
Euclid
It is one of the oldest mathematical sciences developed by the Ancient Greeks. It is concerned with areas, volumes and lengths. Pythagoras and Euclid developed geometry

it is developed because during early people exist their lives they always use geometry in everydays. as the people learn to use it they began doing experiments about these mathematics concern.

I believe that Euclid was referred to as the 'Great Geometer'. What he did was gather and organize into several books all known geometry at his time. So if your definition of 'develop' is to gather information and organize it, then he developed geometry.
Rene Descartes first developed the mathematics of coordinate geometry.
