Construction of the circumcircle of triangle ABC and the circumcenter Q. The circumcenter of a triangle can be constructed by drawing any two of the three perpendicular bisectors. For three non-collinear points, these two lines cannot be parallel, and the circumcenter is the point where they cross.
In geometry, a triangle center or triangle centre is a point in the triangle's plane that is in some sense in the middle of the triangle. For example, the centroid, circumcenter, incenter and orthocenter were familiar to the ancient Greeks, and can be obtained by simple constructions.
An architectural drawing or architect's drawing is a technical drawing of a building (or building project) that falls within the definition of architecture.Architectural drawings are used by architects and others for a number of purposes: to develop a design idea into a coherent proposal, to communicate ideas and concepts, to convince clients of the merits of a design, to assist a building ...
Elevation view of the Panthéon, Paris principal façade Floor plans of the Putnam House. A house plan [1] is a set of construction or working drawings (sometimes called blueprints) that define all the construction specifications of a residential house such as the dimensions, materials, layouts, installation methods and techniques.
The triangle can be inscribed in a semicircle, with one side coinciding with the entirety of the diameter (Thales' theorem). The circumcenter is the midpoint of the longest side. The longest side is a diameter of the circumcircle (=). The circumcircle is tangent to the nine-point circle. [8] The orthocenter lies on the circumcircle.
A regular hendecagon is represented by Schläfli symbol {11}.. A regular hendecagon has internal angles of 147. 27 degrees (=147 degrees). [5] The area of a regular hendecagon with side length a is given by [2]
For a regular n-gon, the sum of the perpendicular distances from any interior point to the n sides is n times the apothem [4]: p. 72 (the apothem being the distance from the center to any side). This is a generalization of Viviani's theorem for the n = 3 case. [5] [6]
Geometry – the shape of the object; represented as views; how the object will look when it is viewed from various angles, such as front, top, side, etc. Dimensions – the size of the object is captured in accepted units. Tolerances – the allowable variations for each dimension. Material – represents what the item is made of.
