Euclidean geometry is one of the oldest branches of mathematics
– the properties of different shapes have been investigated for
thousands of years. For this reason, many tend to believe that today
it is almost impossible to discover new properties and new directions
for research in Euclidean geometry.
In the present paper, we define the concepts of “Pascal
pointsâ€, “a circle that forms Pascal pointsâ€, and
“a circle coordinated with the Pascal points formed by
itâ€, and we shall prove nine theorems that describe the
properties of “Pascal points†on the sides of a convex
quadrilateral.
These properties concern the following subjects:
â— The ratios of the distances between the Pascal points formed
on a pair of opposite sides by different circles.
â— The ratios of the distances between the centers of the circles
“that form Pascal points on the sides of the
quadrilateralâ€, and the ratios of the distances between the
Pascal points formed using these circles.
◠Special types of circles “that form Pascal points on the
sides of a quadrilateralâ€.
â— The properties of Pascal points and the centers of the special
circles defined.
