Points in the Euclidean plane with certain coordinates , , , etc. | |
The line that passes through points and | |
This says that the points , and are collinear, i.e. there exists a unique line which passes through all of them. | |
The segment with endpoints and | |
The length of the segment with endpoints and | |
This says that the lines and are parallel, i.e. they do not have any points in common. | |
This says that the lines and are perpendicular, i.e. they form a right angle at their point of intersection. | |
The distance between the points and | |
The distance between the point and the line | |
The angle with vertex and rays , | |

This says that the triangles and are congruent, which means that | |
This says that the triangles and are similar, which basically means | |
The quadrilateral with vertices , , and | |
