Need some math words that start with I?
From Improper Fraction and Isosceles Triangle to Invariant and Integer, there are some useful math-related words beginning with the letter I.
Here is a list of some of the words I was able to find beginning with I:
Math Words That Start With I
Improper Fraction – a fraction whose numerator is equal to, larger than, or of equal or higher degree than the denominator.
Interval – a set of real numbers between two given numbers called the endpoints of the interval.
Intersect – the intersection of two sets A and B, denoted by {\displaystyle A\cap B, } is the set containing all elements of A that also belong to B or equivalently, all elements of B that also belong to A.
Inverse – Inverse operations are pairs of mathematical manipulations in which one operation undoes the action of the other.
Isosceles Triangle – a triangle that has two sides of equal length.
Inch – a unit of length in the customary system of measurement.
Intersection Lines – a single point where two lines meet or cross each other.
Inequality – a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
Invariant – a property of a mathematical object which remains unchanged after operations or transformations of a certain type are applied to the objects.
Investing – the act of allocating resources, usually money, with the expectation of generating an income or profit.
Irrational Number – the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers.
Irregular Polygon – polygons that have unequal angles and unequal sides, as opposed to regular polygons which are polygons that have equal sides and equal angles.
Isometric – an isometry (or congruence, or congruent transformation) is a distance-preserving transformation between metric spaces, usually assumed to be bijective.
Iteration – the repeated application of a function or process in which the output of each step is used as the input for the next iteration.
Interquartile Range – the difference between smallest value and the largest value of the middle 50% of a set of data.
Interpolation – a type of estimation, a method of constructing new data points based on the range of a discrete set of known data points.
Interior Angle – the inner of the two angles formed where two sides of a polygon come together.
Interest – a process in which an amount of money borrowed or lent increases over time.
Inradius – The radius of the largest circle that will fit inside any given geometric shape, especially inside a regular polygon.
Inscribe – A geometric figure which touches only the sides (or interior) of another figure.
Increase – become or make greater in size, amount, or degree.
Increment – a small positive or negative change in a variable quantity or function.
Independent Variable – a variable (often denoted by x ) whose variation does not depend on that of another.
Infinite – greater than any assignable quantity or countable number.
Inflation – the rate of increase in prices over a given period of time.
Impossible Event – an event that cannot happen.
Integers – a number which is not a fraction; a whole number.
