What are all the shapes and their names?

Shapes often have specific names depending on how many sides they have; a hexagon, for example, has six sides, as the Greek prefix for six is "hex." As there is no limit to how many sides a shape may have, there is no realistic way to compile a complete list of shapes. Shapes can be regularly named, however.\nSome commonly understood, and uniquely named, two-dimensional shapes are squares, triangles and circles. Shapes with three through twenty sides often have unique names; above that, the names are constructed based on Greek or Latin prefixes. A 78-sided polygon, for example, would be a hept..

What is the meaning of "triangulation?"

Triangulation can also be used in psychology to mean a situation in which one family member refuses to communicate directly with another family member, but communicates with that person through a third family member, forming a triangle. When used in the social sciences, this term indicates that two or more methods are used in a study in order to increase the reliability of the results.

How is a rhombus similar to a square?

A rhombus is one of several types of four-sided shapes known as quadrilaterals. Other quadrilaterals are rectangles, parallelograms, kites and trapezoids. In addition to the square, a rhombus is similar to a parallelogram because both shapes have two sets of parallel sides. While all rhombuses are parallelograms, a parallelogram is not a rhombus because it does not have four equal sides. The area of a rhombus can be calculated by multiplying its height by its side length. The perimeter is calculated by multiplying the length of a side by four.

What is a complex problem?

Complex problems can be of an epistemological nature—involving questions related to the nature and scope of human knowledge—or they can involve philosophical questions concerning ontology or the nature of being. Epistemologically complex problems may concern, for example, the status of an object of art. What constitutes a work of art is a problem that cannot be sufficiently answered through axiomatic or reductive thinking. Only answers that addresses art's role within society, its philosophical consequences and its historical development—in short, a multifarious and highly complex s..

What distinguishes a histogram from a bar chart?

In bar charts, the bars or categories can be rearranged in any way, alphabetically or by size. In histograms, the bars represent the percentage or distribution of values per range of grouped data. Because of the continuity of the information presented, it is not logical to rearrange the bars in histograms.\nAnother distinction is that histograms don't have spaces in between the bars unless a range has zero value. Bar charts can have spaces in between since each one is independent of the other. In addition, the bars of bar charts are typically drawn to have the same width, but this is not ..

How many edges does a hexagonal prism have?

A hexagonal prism is the basic three-dimensional representation of a hexagon, which is a two-dimensional polygon with six sides. The prism consists of two hexagons that are parallel to each other, which may or may not be the same size. They are connected with straight lines from a vertex on one hexagon to a vertex on the other. The connecting lines form quadrilaterals on the sides, either squares or rectangles. In total, a hexagonal prism has eight faces, with six quadrilateral faces and two hexagon faces. Additionally, a hexagonal prism also has 12 vertices, six located at each vertex of each..

How do you use mathematics formulas to solve problems?

There are many formulas used in math, including those for area, surface area, work, distance, perimeter and compound interest, but the same basic steps are required to solve them. Identify the necessary formulaRead the problem to understand what it is asking and what the known variables are. Identify the correct formula to use and plan out a strategy to solve for the specified variable.Solve the problem using the formulaUse the formula and solve in terms of the known variable. Do this by rearranging the known variables in the formula, performing operations so that the specified variable is the..

How do you estimate fractions with mixed numbers?

Choose benchmarks for the fraction in the mixed numberThe benchmark is the reference for estimating the fraction. Let 0, 1/2 and 1 be the benchmarks for the fraction.Determine whether the fraction is closest to 0, 1/2 or 1If the numerator is very small compared to the denominator, select 0 as the benchmark. For example, with 5/100, the numerator, 5, is very small compared to the denominator, 100; therefore, 0 is the benchmark. If the numerator is nearly half the denominator, choose 1/2 as the benchmark. For example, with 50/120, 50 is nearly half the value of 120; therefore, 1/2 is the benc..

Why do we need probability?

Probability can be represented numerically with a number between zero and one, with zero representing the impossibility of something specific happening and one representing the certainty of that thing happening. This number is often transferred to a percentage in order to predict something useful, such as a weather person predicting the likelihood of rain on the following day. Such an individual uses probability by taking available data on weather and making the most accurate prediction possible. Probability theory differs from statistics because statistics requires the examination of what has..

How do you calculate population density?

Determine the locationChoose the unit of physical space that is to be used. Population density is a measurement of the number of people per unit area. That unit area can be small, such as a neighborhood, or large, such as a country or continent. Calculate the areaA common measurement used when speaking of population density is square mile. Either measure the physical area or locate the length and width from a reliable resource, such as a map.Find the population countLearn the population count present within the boundaries of the area. Depending on the size of the area, you might consult offici..
