Euclid S Elements Book I Proposition 3 Given Two Unequal Straight That circle will cut off the correct length from the longer line. no new definitions, postulates, or common notions are needed in the proof of i.3. as mentioned in the guide to i.3, this proposition is used more than any other proposition in the elements. Let ab and c be the two given unequal straight lines, and let ab be the greater of them. it is required to cut off from ab the greater a straight line equal to c the less. i.2. i.post.3. place ad at the point a equal to the straight line c, and describe the circle def with center a and radius ad. i.def.15.
Euclid S Elements Book I Proposition 3 Given Two Unequal Straight Proclus (p. 357, 9) explains that euclid uses the word alternate (or, more exactly, alternately, ἐναλλάξ) in two connexions, (1) of a certain transformation of a proportion, as in book v. and the arithmetical books, (2) as here, of certain of the angles formed by parallels with a straight line crossing them. Proposition 3. given two unequal straight lines, to cut off from the greater a straight line equal to the less. let ab, c be the two given unequal straight lines, and let ab be the greater of them. thus it is required to cut off from ab the greater a straight line equal to c the less. at the point a let ad be placed equal to the straight line c. Reference page. book i. (postulate 1) to draw a straight line from any point to any point. (postulate 2) to produce a finite straight line continuously in a straight line. (postulate 3) to describe a circle with any center and radius. (postulate 4) that all right angles equal one another. (postulate 5) that, if a straight line falling on two. A point is that which has no part. definition 2. a line is breadthless length. definition 3. the ends of a line are points. definition 4. a straight line is a line which lies evenly with the points on itself. definition 5. a surface is that which has length and breadth only.

The elements (greek: Στοιχεῖα stoikheîa) is a mathematical treatise consisting of 13 books attributed to the ancient greek mathematician euclid c. 300 bc. it is a collection of definitions, postulates, propositions (theorems and constructions), and mathematical proofs of the propositions. the books cover plane and solid euclidean. 4654912 the first six books of the elements of euclid in which coloured diagrams and symbols are used instead of letters for the greater ease of learners — book i. prop. xi. prop. 1847 oliver byrne rom a given point ( ), in a given straight line ( ), to draw a perpendicular.
