Euclidean geometry is a form of geometry first codified by Euclid in his series of thirteen books, The Elements.
Concepts
Some of the concepts used and described in Euclidean geometry are:
- A point is a mathematical object which has a position but neither length nor breadth nor depth.
- line or straight line
- surface
- plane
- plane angle
- rectilinear angle or angle including
- parallel
- perpendicular
- boundary
- figure
- plane figure
- circle
- center
- diameter
- semicircle
- trilateral
- quadrilateral
- multilateral
- equilateral
- congruence
- similarity
- rigid motion
- dilation
