...angles, and there remain all the outward angles equal to four right angles (by ax. 3). THEOREM XXI. A PERPENDICULAR is the Shortest Line that can be drawn from a Given Point -to an Indefinite Line. And, of any other Lines drawn from the same Point, those that are Nearest the Perpendicular,... | |

...Now AF is less than AC + CF (theorem 7) ; therefore, taking the halves, AB is less than AC ; that is, the perpendicular is the shortest line that can be drawn from A to DE. Next, suppose BE equal to BC ; then the triangles ABE and ABC will be equal (t/ieonm 5), for... | |
