3 days ago · A cyclic quadrilateral is a four-sided polygon whose vertices lie on a circle, so all its angles are inscribed angles in the circle. In a cyclic quadrilateral, the angle created by a diagonal and a side is equal in measure to the angle created by the other diagonal and the opposite side, because they are subtended by the same arc in the circle.
1 day ago · contributed. Polygons are two-dimensional geometric objects composed of points and straight lines connected together to close and form a single shape. Irregular polygons are polygons that have unequal angles and unequal sides, as opposed to regular polygons which are polygons that have equal sides and equal angles. Irregular Polygons.

2 days ago · 3D model of a regular tetrahedron. In geometry, a tetrahedron ( pl.: tetrahedra or tetrahedrons ), also known as a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertices. The tetrahedron is the simplest of all the ordinary convex polyhedra.

5 days ago · A polygon has n n sides. Two of its exterior angles are 72 degrees and 35 degrees, while the remaining exterior angles are each equal to 23 degrees. Find the value of n n. A simple closed figure made up of only line segments is called a polygon. We generally classify polygons according to the number of sides (or vertices) they have.
2 days ago · Around 265 AD, the Wei Kingdom mathematician Liu Hui created a polygon-based iterative algorithm and used it with a 3,072-sided polygon to obtain a value of π of 3.1416. [52] [53] Liu later invented a faster method of calculating π and obtained a value of 3.14 with a 96-sided polygon, by taking advantage of the fact that the differences in ...
2 days ago · A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft-mounted permanent magnet mechanism, and current is induced into the stationary armature.
