Vertices are the points, or corners, in geometrical and mathematical shapes where two or more lines meet but do not cross, according to Math Open Reference. Vertices can exist in two-dimensional and three-dimensional shapes. The singular form of vertices is vertex. Sometimes, the term vertex is also used to describe certain points on quadratic equations.Know More
Vertices are often used as a description of the corner of a shape, generally a polygon. However, they can also exist at a point between any two lines which meet and form an angle but do not cross. If the lines cross, the point is considered an intersection and not a vertex. Vertices are a useful way to describe objects and their placement in two-dimensional and three-dimensional spaces. Two-dimensional objects have vertices where their lines meet, and three-dimensional objects have vertices where their planes meet. In this sense, vertices can sometimes be described as the corners of a geometric structure.
In mathematics, the term vertex can also refer to the peak of a parabola. A parabola is a curved shape that is generated by graphically representing a quadratic equation. The peak of a parabola is either the highest or lowest point on the curve, depending on whether it opens upwards or downwards.Learn more about Data Graphs
Calculating depreciation depends on the item you are depreciating, and whether you want to calculate by time or by use. Three methods of calculating depreciation exist: the declining balance method, the straight line method and the sum of the year's digits method. In the declining balance method, depreciation equals the book value multiplied by the depreciation rate. The book value is equal to the cost minus the accumulated depreciation.Full Answer >
Math facts, or math fluency facts, are the basic rules of calculation that enable elementary school students to solve common math problems. An understanding of these basic rules and facts is required to perform common fifth-grade level math calculations. An elementary school student's proficiency in solving math problems at their educational level is relative to how well they can accurately and quickly recall and apply basic multiplication, division, addition and subtraction facts.Full Answer >
A segmented bar graph is similar to regular bar graph except the bars are made of different segments that are represented visually through colored sections. A segmented bar graph is sometimes known as a stacked bar graph, and it offers greater detail about data sets.Full Answer >
