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'...
Vertical angles对顶角: vertical angles are congruent Transversal横断的:穿过两条平行线的直线 Triangles - part 1 1) the sum of the three angles in any triangle must be 180 degree 2) two angles of a triangle must be acute锐角;the third could be acute, right直角, or abtuse钝角 3) biggest ...

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...
By the sum of angles of a triangle, we can also get the third angle of the isosceles triangle which happens to be a central angle. The third angle of the isosceles triangle is equal to twice the angle formed by the chord and the tangent line. Now, the central angle subtends an arc ...
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...
While algebra and calculus represent difficult subjects for some students, geometry also constitutes a potentially challenging subject, as it studies both two-dimensional and three-dimensional shapes in terms of their angles and properties. Central to any geometry class is the use of geometry proofs ...
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...

Geometry is a branch ofmathematicsthatdealswith the study of shapes, sizes, positions, and the relationships between them. It is concerned with the study of points, lines, angles, surfaces, and solids, and how they can be represented, measured, and manipulated. These relationships can be expres...
