trisector การใช้

• In the mathematics of paper folding, the angle-trisector.
• The first trio recording, " Trisector ", was released on 17 March 2008.
• Bricard also gave one of the first geometric proofs of Morley's trisector theorem in 1922.
• An aluminum trisector ( three-part ) fairing derived from the Titan IV fairing is also available.
• Morley's trisector theorem states that the Morley triangle of any triangle is always an equilateral triangle.
• As 11 is not a Fermat prime, the regular hendecagon is not even with the usage of an angle trisector.
• A cubic equation with real coefficients can be solved geometrically using angle trisector if and only if it has three real roots.
• A typical structure is the trisector, also known as clover, in which there are three sectors served by separate antennas.
• Since 70 = 2 ?5 ?7, a regular heptacontagon is not constructible using a compass and straightedge, but is constructible if the use of an angle trisector is allowed.
• Since 42 = 2 ?3 ?7, a regular tetracontadigon is not constructible using a compass and straightedge, but is constructible if the use of an angle trisector is allowed.
• Since 50 = 2 ?5 2, a regular pentacontagon is not constructible using a compass and straightedge, and is not constructible even if the use of an angle trisector is allowed.
• Since 90 = 2 ?3 2 ?5, a regular enneacontagon is not constructible using a compass and straightedge, but is constructible if the use of an angle trisector is allowed.
• The smallest prime that is not a Pierpont ( or Fermat ) prime is 11; therefore, the hendecagon is the smallest regular polygon that cannot be constructed with compass, straightedge and angle trisector.
• *If I am reading ( and part guessing ) right, your construction rests upon the presumption that " In an isosceles triangle, the angle trisector of the vertex angle, trisects the base ".
• Since 360 = 2 3 ?3 2 ?5, a regular 360-gon is not constructible using a compass and straightedge, but is constructible if the use of an angle trisector is allowed.
• Indeed, it is not even constructible with the use of neusis or an angle trisector, as the number of sides is neither a product of distinct Pierpont primes, nor a product of powers of two and three.
• In some sources a full circle rather than a semicircle is used, or the tomahawk is also thickened along the diameter of its semicircle, but these modifications make no difference to the action of the tomahawk as a trisector.
• While it is impossible to construct a perfect regular 56-sided polygon using a compass and straightedge, a close approximation has recently been discovered which it is claimed might have been used at Stonehenge, and it is constructible if the use of an angle trisector is allowed since 56 = 2 3 ?7.
