| parallel | In geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. By extension, a line and a plane, or two planes, in three-dimensional Euclidean space that do not share a point are said to be parallel. |
| perimeter | The perimeter of a polygon is the distance around the outside of the polygon. |
| pi | 3.14159265359 |
| plot | Plot is a narrative (and, traditionally, literary) term defined as the events that make up a story, particularly: as they relate to one another in a pattern or in a sequence; as they relate to each other through cause and effect; how the reader views the story; or simply by coincidence. |
| polygon | a plane figure that is bounded by a finite chain of straight line segments closing in a loop to form a closed chain or circuit. |
| power | |
| prime number | |
| product | a quantity obtained by multiplying quantities together, or from an analogous algebraic operation. |
| proof | |
| protractor | A protractor is a measuring instrument, typically made of transparent plastic or glass, for measuring angles. Most protractors measure angles in degrees (°). |
| pyramid | a structure whose outer surfaces are triangular and converge to a single point at the top, making the shape roughly a pyramid in the geometric sense. The base of a pyramid can be trilateral, quadrilateral, or any polygon shape, meaning that a pyramid has at least three outer triangular surfaces (at least four faces including the base). The square pyramid, with square base and four triangular outer surfaces, is a common version. |
| quotient | In mathematics, a quotient (from Latin: quotiens "how many times", pronounced ˈkwoʊʃənt) is the result of division. For example, when dividing 6 by 3, the quotient is 2, while 6 is called the dividend, and 3 the divisor. |
| radian | The radian is the standard unit of angular measure, used in many areas of mathematics. An angle's measurement in radians is numerically equal to the length of a corresponding arc of a unit circle; one radian is just under 57.3 degrees (when the arc length is equal to the radius). |
| rational number | In mathematics, a rational number is any number that can be expressed as the quotient or fraction p/q of two integers, p and q, with the denominator q not equal to zero. Since q may be equal to 1, every integer is a rational number. |
| radius | In classical geometry, the radius of a circle or sphere is the length of a line segment from its center to its perimeter. |
| real number | The real numbers include all the rational numbers, such as the integer −5 and the fraction 4/3, and all the irrational numbers such as √2 (1.41421356…, the square root of two, an irrational algebraic number) and π (3.14159265…, a transcendental number). |
| rectangle | |
| remainder | In mathematics, the remainder is the amount "left over" after performing some computation. In arithmetic, the remainder is the integer "left over" after dividing one integer by another to produce an integer quotient (integer division). |
| right angle | In geometry and trigonometry, a right angle is an angle that bisects the angle formed by two halves of a straight line. More precisely, if a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles. |
| rounded | having a smooth, curved surface. well developed in all aspects; complete and balanced. |
| series | a group or a number of related or similar things, events, etc. |
| sine | in mathematics, is a trigonometric function of an angle. The sine of an angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (i.e., the hypotenuse). |
| slope | the slope or gradient of a line is a number that describes both the direction and the steepness of the line. Slope is often denoted by the letter m. The direction of a line is either increasing, decreasing, horizontal or vertical. A line is increasing if it goes up from left to right. |
| solve | |
| square root | |
| symmetry | the quality of being made up of exactly similar parts facing each other or around an axis. |
| tangent | In geometry, the tangent line (or simply tangent) to a plane curve at a given point is the straight line that "just touches" the curve at that point. Leibniz defined it as the line through a pair of infinitely close points on the curve. |
| trapezoid | A trapezoid is a 4-sided flat shape with straight sides that has a pair of opposite sides parallel. Called an Isosceles trapezoid when the sides that aren't parallel are equal in length and both angles coming from a parallel side are equal. |
| union | in mathematics, a fundamental operation and relation of sets |
| unit | |
| variable | |
| vertex | In geometry, a vertex (plural vertices) is a special kind of point that describes the corners or intersections of geometric shapes. |

| isosceles | An isosceles triangle is a triangle with (at least) two equal sides |
| null | zero, null, nil, nothing, naught, invalid, null, to no avail, of no avail |
| parabola | The parabola is the curve formed from all the points (x, y) that are equidistant from the directrix and the focus. The line perpendicular to the directrix and passing through the focus (that is, the line that splits the parabola up the middle) is called the "axis of symmetry" |
| parallelogram | In Euclidean geometry, a parallelogram is a (non self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. |
| perpendicular | In elementary geometry, the property of being perpendicular (perpendicularity) is the relationship between two lines which meet at a right angle (90 degrees). The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle. |
| polyhedron | In geometry, a polyhedron is simply a three-dimensional solid which consists of a collection of polygons, usually joined at their edges. The word derives from the Greek poly (many) plus the Indo-European hedron (seat). |
| polynomial | an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s). an expression consisting of variables (or indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents. |
| quadratic | In mathematics, the term quadratic describes something that pertains to squares, to the operation of squaring, to terms of the second degree, or equations or formulas that involve such terms. Quadratus is Latin for square. |
| quadrilateral | A quadrilateral is a four-sided polygon with four angles. There are many kinds of quadrilaterals. The five most common types are the parallelogram, the rectangle, the square, the trapezoid, and the rhombus. |
| scientific notation | |
| torus | In geometry, a torus (plural tori) is a surface of revolution generated by revolving a circle in three-dimensional space about an axis coplanar with the circle. If the axis of revolution does not touch the circle, the surface has a ring shape and is called a ring torus or simply torus if the ring shape is implicit. |
| Venn diagram | a diagram representing mathematical or logical sets pictorially as circles or closed curves within an enclosing rectangle (the universal set), common elements of the sets being represented by the areas of overlap among the circles. |
