EBM1 is a similar triangle to fof' so Thus M1 is the point where the eye views the first family of measuring parallels; thus M1 is the vanishing point for this set of parallels. This proof assignment addresses basic angle relationships that exist when two parallel. In essence, a projective geometry may be thought of as an extension of Euclidean geometry in which the "direction" of each line is subsumed within the line as an extra "point", and in which a "horizon" of directions corresponding to coplanar lines is regarded as a "line".
