## Types of Functions: Definition & Examples

The types of functions are determined by the domain, range, and function expression. Functions are primarily defined by the expression they are written in. Furthermore, the relationship between the elements of the domain set and the range set also accounts for the type of function. The classification of functions makes it easier to understand and … Read more

## Mean Median Mode – Difference, Formula, and Examples

In statistics, the mean, median, and mode are the three measures of central tendency. While describing a data set, we identify the central position of the data. This is known as a measure of central tendency. We come across data every day. Newspapers, articles, bank statements, mobile and electricity bills contain them. It is impossible … Read more

## What is Scalene Triangle – Properties, Formulas, and Examples

The scalene triangle is the triangle with all unequal sides. All three sides of the triangle are unequal, so all three angles are also different in length. Based on the properties of its sides, it is one of three types of triangles. A scalene triangle is one in which none of the sides are equal. … Read more

## Lines, Segments, and Rays: Definition and Difference

Lines, Segments, and Rays: Although we all identify intuitively what a line is, it is actually difficult to give a good mathematical definition. Cruelly, we can say that a line is an infinitely thin, infinitely long collection of points extending in two opposite directions. When we form lines in geometry, we use an arrow at each … Read more

## Alternate Interior Angles: Definition, Theorem, and Proofs

Alternate interior angles are the angles made on the opposite sides of the transversal. In other words, when two parallel lines are crossed by a transversal, eight angles are formed. Among these, the angles that lie on the inner side of the parallel lines but on the different sides of the transversal are known as … Read more

## Converse Statement: Definition and Explanation

The three most common ways to change a conditional statement are by taking its inverse, its converse statement, or its contrapositive. In each case, either the hypothesis or the conclusion swap places, or a statement is replaced by its negation. The Inverse Statement A conditional statement is reversed by replacing the hypothesis and the conclusion … Read more

## Rounding Decimals: Methods, Examples, and Solutions

Rounding Decimals: Utilizing a calculator often gives a long string of digits. For instance, 1 ÷ 3 might give .333333333. But very often, for practical goals, this level of accuracy is too precise to be useful. You try measuring .33333333 meters! Decimal numbers can be rounded quite like whole numbers. For example, 0.33333333 is nearer … Read more

## One to One Function – Definition, Properties, & Examples

Relationships one to one function refer to relationships between any two items in which one can only belong to one other item. In a mathematical sense, these relationships are known as one-to-one functions, in which there are equal numbers of items or in which one item is paired with only one other item. The name … Read more

## Place Value: Decimals Comparisons and Hundredths Place in Decimals

There are terms that describe place value for decimals in the same way that those terms describe place value for whole numbers, such as tenths, hundredths, thousandths, ten thousandths, hundred thousandths, millionths, etc. Beginning with the first numeral after the decimal point, these terms are used from left to right. In the number 0.1234, there … Read more

## How to Find Axis of Symmetry – Formula, Equation, and Examples

The axis of symmetry is a straight line that divides an object into two identical parts, thus creating one part as a mirror image of another. Folded along the axis of symmetry, the two parts become superimposed. In terms of symmetry, the mirror line is the straight line. The horizontal, vertical, or slanting line can … Read more
