말뭉치
- The assertion that every ruler-and-compass construction could be accomplished with a compass is due to Lorenzo Mascheroni (1750-1800) and appeared in his 1797 tractate The Geometry of Compasses.[1]
- Stated this way, ruler and compass constructions appear to be a parlor game, rather than a serious practical problem.[2]
- In ruler and compass construction, one starts with a line segment of length one.[2]
- GRACE is an interactive ruler and compass construction editor for use in teaching the fundamental concepts of geometry to high school students.[3]
- GRACE allows dynamic creation and modification of ruler and compass constructions, allowing students to easily visualize the steps of a construction and how it varies for different inputs.[3]
- The classical constructions are called Euclidean constructions, but they certainly were known prior to Euclid.[4]
- Dürer goes on to give ruler and compass constructions of regular polygons with sides numbering 3, 4, 5, 6, 7, 8, 9, 11, and 13.[5]
- Practice Problem : Use classical construction techniques to divide the isosceles triangle below into two congruent right triangles.[6]
- Ruler-and-compass constructions only use undivided rulers, and compasses.[7]
- (Note: P.E.Zimourtopoulos of the Democritus University of Thrace, Greece, reminded me, that strict ruler-and-compass constructions cannot use compasses in this last mentioned way.[7]
- A geometric figure is constructible if it can be made from a compass and straightedge construction.[8]
- One has to be very careful with the terminology associated with compass and straightedge constructions.[8]
