There are both golden triangles and golden rectangles. In order to be considered golden the ratio must be the same as the sum of the longest side to the other two sides.
when golden rectangle constructed?
phi is incorperated into the golden rectangle, because if you divide the longer side of the golden rectangle by the shorter sid, the answer will be phi.(1.168...)
Euclid was the one to construct the golden rectangle
A golden rectangle is a rectangle whose side lengths are in the golden ratio, approximately 1:1.618. A 3x5 card has side lengths of 3 inches by 5 inches, which do not match the golden ratio. Therefore, a 3x5 card is not a golden rectangle.
true
No, there's no golden pentagon.
conclusion
The Golden Rectangle is a geometrical figure whose side lengths are in the golden ratio. It can be made with only a compass and a straight edge.
