Blog Introduction: Arcs and subtended angles are two basic concepts in geometry. An arc is a part of a circle, and a subtended angle is an angle that is created by two points on the arc. These concepts can be used to solve various types of problems related to circles and angles. Let'...

Angles can have several interpretations and can be represented as a number, a text, or a well formed array. This function takes one input representation and converts it to another. The input value is described by a dictionary that specified the type of angle and the type of direction. Examp...
Arc of a Circle:An arc of a circle is referred to as a curve that is a part or portion of its circumference. Acute central angles will always produce minor arcs and small sectors. When the central angle formed by the two radii is 90o, the sector is called a quadrant because the tota...

Plane Geometry- A two dimensional figure, also called planar geometry, with edges. The edges are line segments or edges and curve segments or arcs, all lying on a flat plane. Plastic Section Modulus (Z)- Used to determine the limit state of a structural beam defined as the point when the...
Sum of 3 angles in the triangle =π= 1/2 (2π) =1/2 circle => its Area = 1/2(π. 2^2) = 2π = Sum of 3 arcs’ area The excellent and unique Geometry book is available at below link or 友谊书局 (新加坡 百胜楼 3楼 Bras Basah Complex, Victoria Street): ...
The basic goal of that geometry is to find relationships between lengths and angles in triangles and other polygons. Knowledge of such relationships then provides a basis for the calculation of the surface areas and volumes of certain solids. The central concepts underlying school geometry are the...
