Looking for Math words that start with P?

If you’re interested in Math, you will have noticed Math has its own language for the most part, but that’s part of the fun!

If you’re interested in math-related words beginning with the letter P, the below list should come in handy:

## Math Words That Start With P

**Pair **– a pair of objects.

**Parallel **– (of lines, planes, or surfaces) side by side and having the same distance continuously between them.

**Parallel Lines** – lines which are always the same distance apart and never meet.

**Parallelogram **– a quadrilateral with opposite sides parallel and equal.

**Parentheses **– a pair of symbols used to enclose sections of a mathematical expression, often called brackets.

**Partial Quotient** – a method for solving large division problems in mathematics.

**Partitive Division** – involves sharing a quantity (dividend) between a given number (divisor) of equal-sized groups.

**Pascal’s Triangle** – triangular array of the binomial coefficients that arises in probability theory, combinatorics, and algebra.

**Pattern **– a series or sequence that repeats.

**Pentagon **– In geometry, a pentagon is any five-sided polygon or 5-gon.

**Pentagonal Prism** – a three-dimensional box whose bottom and top have five sides instead of the normal four.

**Pentagonal Pyramid** – a pyramid with a pentagonal base upon which are erected five triangular faces that meet at a point (the vertex).

**Pentagram **– the simplest regular star polygon.

**Percent **– a relative value indicating hundredth parts of any quantity.

**Perimeter **– the boundary of a closed plane figure.

**Period **– a number that can be expressed as an integral of an algebraic function over an algebraic domain.

**Perpendicular **– lines that intersect at a 90-degree angle.

**Pi **– the ratio of the circumference of any circle to the diameter of that circle.

**Picture Graph** – a graph used to display information that uses images or symbols to represent data.

**Pint **– a unit of liquid measure of capacity equal to one eighth of a gallon.

**Plane **– a flat, two-dimensional surface that extends indefinitely.

**Platonic Solids** – a convex regular polyhedron in three-dimensional Euclidean space.

**Plot **– a graphical technique for representing a data set, usually as a graph showing the relationship between two or more variables.

**Point **– an individual detail.

**Polygon **– any closed curve consisting of a set of line segments (sides) connected such that no two segments cross.

**Polyhedron **– a three-dimensional object composed of a finite number of polygonal surfaces (faces).

**Polynomial **– an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

**Power Function** – a function where y = x ^n where n is any real constant number.

**Prime Number** – a number that can only be divided by itself and 1 without remainders.

**Prism **– a 3D shape that has two identical shapes facing one another.

**Probability **– the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

**Problem **– a question which needs a mathematical solution.

**Product **– the result of one or more multiplications.

**Projection **– a correspondence between the points of a figure and a surface (or line).

**Proof **– an inferential argument for a mathematical statement, showing that the stated assumptions logically guarantee the conclusion.

**Protractor **– a group of instruments used to construct and measure plane angles.

**Pyramid **– a polyhedron for which the base is a polygon and all lateral faces are triangles.

**Pythagoras Theorem** – geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.
