If we know the slope m, but we do not know the coordinates of the point where the line is tangent to the curve, we can clear the x from the previous formula. Other times we are asked that the tangent line should be parallel to another given line. Two parallel lines have the same slope, so from the given line, we can obtain the slope. parallelto a given line through a given point with compass and straightedge or ruler. This construction works by creating a Since we know that the opposite sides of a rhombus are parallel, then we have created the desired parallel line. angle copy methodsince it is done with just a single compass setting.

Through a point not on a given straight line, one and only one line can be drawn that never meets the given line. The fifth postulate is called the parallel postulate. Euclid used a different version of the parallel postulate, and there are several ways one can write the 5th postulate. They are all equivalent and lead to the same geometry.

Simply stated, this Euclidean postulate is: through a point not on a given line there is exactly one line parallel to the given line. In hyperbolic geometry, through a point not on a given line there are at least two lines parallel to the given line. The tenets of hyperbolic geometry, however, admit the other four Euclidean postulates.

But the origin of this force was a mystery for hundreds of years. Einstein's theory of general relativity is a theory which does an excellent job of solving this mystery: it views mass as warping the space around it such that the space becomes non-Euclidean, that is the shortest distance between two points is not a straight line.

Hyperbolic geometry is the geometry you get by assuming all the postulates of Euclid, except the fifth one, which is replaced by its negation. In hyperbolic geometry there exist a line and a point not on such that at least two distinct lines parallel to pass through .
