These increased capabilities make it possible to construct otherwise unconstructible numbers, but are at odds with the typical understanding of “straight-edge and compass” in the mathematical community. The answer by Viking uses a more physical interpretation of the ruler, and also allows for incremental adjustments (sliding the ruler). Which toolsĪll the above refers to the canonical interpretation of ruler and compass, where the ruler may only be used to connect two points, or to extend a segment. In fact $k=2^3\cdot3\cdot5=120$ leads to $3°$ as the smallest integer number of degrees which can be constructed.Īlso see the Wikipedia or MathWorld page on constructible regular polygons. For $k=360=2^3\cdot3^2\cdot5$ all the prime factors are indeed Fermat primes, but the exponent at $3^2$ is a problem, making this non-constructible. The accepted answer there points out that $k=2^\alpha\cdot p_1\cdots p_s$ works if all the $p_s$ are distinct Fermat primes. ![]() For more advanced use to create angle problems in which the missing letter angle values have to be found. At its most basic for teaching about types of angles, acute, obtuse or reflex. I hadn't looked at this when I first wrote my answer, but the comment by points out Can a circle's circumference be divided into arbitrary number of equal parts using straight edge and compass only? That question essentially asks whether one can construct $360°/k$ for arbitrary integers $k$, so you are dealing with the special case $k=360$. The online protractor tool can be used to practice measuring angles. That line would have a distance from the origin which is You could draw a line through the resulting point perpendicular to one of the legs of the angle. Then you could simply add that angle to itself a number of times to end up with $40°$. So, get ready to find and buy all your desirable products from your best-loved brands on Ubuy.Suppose you could construct $1°$ in the unit circle.
