Euclidean geometry is a form of geometry first codified by Euclid in his series of thirteen books, The Elements.
Some of the concepts used and described in Euclidean geometry are:
- point
- line or straight line
- surface
- plane
- plane angle
- rectilinear angle or angle including
- parallel
- perpendicular
- boundary
- figure
- circle
- center
- diameter
- semicircle
- rectilinear figure
- trilateral
- quadrilateral
- multilateral
- equilateral triangle
- isoscelese triangle
- scalene triangle
- right angled triangle
- obtuse angled triangle
- acute angle triangle
- equilateral
- square
- oblong
- rhombus
- rhomboid
- trapezia
