This is the forty second proposition in euclid's first book of the elements. this construction proof shows that you can build a parallelogram that is equal i.

Euclid S Elements Book 1 Proposition 42 Youtube This is the forty third proposition in euclid's first book of the elements. this proof shows that the complements of the parallelogram about the diameter are. Many of the propositions in the elements, especially those in book i, directly depend on the preceding proposition. postulates 1 and three are used again, and for the first time post.2, which allows a finite straight line to be extended indefinitely. also i.def.15, about equal radii in a circle, is used again, as is c.n.1. A plane surface is a surface which lies evenly with the straight lines on itself. definition 8. a plane angle is the inclination to one another of two lines in a plane which meet one another and do not lie in a straight line. definition 9. and when the lines containing the angle are straight, the angle is called. Proposition $7$: first element of geometric sequence that divides last also divides second. proposition $8$: geometric sequences in proportion have same number of elements. proposition $9$: elements of geometric sequence between coprime numbers. proposition $10$: product of geometric sequences from one.

Later, in proposition ii.14 a square is constructed equal to a given rectilinear figure, a process called quadrature (making into a square) of the figure. this square is a canonical measure of the area. use of proposition 42 this construction is used as part of the constructions in the two propositions following the next one.
