Polygons
... instead of a tetragon, when all the others are ___-gons? Why is there not a single consistent term? Well there really is no answer on why, but it just happened to happen that way. GREAT ANSWER, HUH? "________________" uses the Latin "angle" (angulus) rather than the Greek "gon" which means the same ...

Basic Theorems of Euclidean Geometry We finally adopt the
... (Euclid’s Postulate V) If two lines in the same plane are cut by a transversal so that the sum of the measures of a pair of interior angles on the same side of the transversal is less than 180, then the lines will meet on that side of the transversal. ...

Parallels and Euclidean Geometry Lines l and m which are coplanar
... Theorem If two coplanar lines are cut by a transversal so that some pair of alternate interior angles are congruent, then the two lines are parallel. // Proposition i.29 is the converse of this theorem, but it is not a theorem of absolute geometry: to prove it, Euclid made use of a new axiom, his l ...

Plane Separation, Interior of Angles, Crossbar Theorem
... D4 brings on some startling properties. First notice that the points of a line are placed in a one-to-one relationship with the real number line. For the first time, we’ve got lines with an uncountable infinity of points on them – no finite geometries with 3 points on a line made of some “line stuff ...

Convexity of spheres in a manifold without conjugate points
... MS received 13 February 2002; revised 17 August 2002 Abstract. For a non-compact, complete and simply connected manifold M without conjugate points, we prove that if the determinant of the second fundamental form of the geodesic spheres in M is a radial function, then the geodesic spheres are convex ...
