State the steps used to construct a segment of length d such that a/b =c/d given three other segments of length a, b and c O.o
I mean, the method and the justification?
using only a compass and straight-edge: 1: construct a triangle consisting of sides a and b (given) 2: construct length c along side a. 3: copy (angle A at C, by construction) 4: draw CD.
of course this works if a>c... you can make adjustments to this construction if a<c....
