Math A-Z: Concepts and Definitions

Letters A-Z In Math . By: Izhar Caban, and Andy Wilson

A is for Angle • An angle is two rays sharing a common end point

B is for Base • The bottom of a geometric figure, note both the bottom and top of the figure are the base

C is for Cube • A regular polyhedron for which all faces are squares

D is for Diameter • A line segment between two points on the circle or sphere which passes through the center. The word diameter is also also refers to the length of this line segment

E is for Equilateral Triangle • A triangle with three congruentsides

F is for Formula • An expression used to calculate a desired result, such as a formula to find volume or a formula to count combinations. Formulas can also beequations involving numbers and/or variables, such as Euler's formula

G is for Geometry • The study of geometric figures in two dimensions (plane geometry) and three dimensions (solid geometry). It includes the study of points, lines,triangles, quadrilaterals, other polygons, circles, spheres, prisms, pyramids, cones, cylinders, and polyhedra. Geometry typically includes the study of axioms, theorems, and two-column proofs

H is for Heptagon • A polygon with seven sides. Some authors also use the name septagon instead of heptagon

I is for Isosceles • A triangle with two sides that are the same length. Formally, an isosceles triangle is a triangle with at least two congruent sides.

J is for AdJacent • Two angles in a plane which share a common vertex and a common side but do not overlap. Angles 1 and 2 below are adjacent angles

K is for sKew • Lines in three dimensional space that do not intersect and are not parallel.

L is for Line • The geometric figure formed by two points. A line is the straight path connecting two points and extending beyond the points in both directions.

M is for Measurement • The process of assigning a number to a physical property. Examples of measurement include length, size of an angle, area, volume, mass, time, etc.

N is for Numbers • a numeral or group of numerals. • the sum, total, count, or aggregate of a collection of units 5-a number

O is for Obtuse Angle • An angle that has measure more than 90° and less than 180°.

P is for Parallelogram • A quadrilateral with two pairs of parallelsides.

Q is for Quadrilateral • A polygon with four sides.

R is for Right Angle • A 90° angle.

S is for Sphere • A three dimensionalsolid consisting of all points equidistant from a given point. This point is the center of the sphere. Note: All cross-sections of a sphere are circles.

T is for Trapezoid • US usage, definition 1: A quadrilateral which has a pair of opposite sides which are parallel. The parallel sides are called the bases, and the other two sides are called the legs.

U is for Unit of Measurement • any division of quantity accepted as a standard of measurement or exchange ‘Pounds , and Ounces are units of measurment

V is for Vertices • The highest point; the top or apex.

W is for Width • The measurement or extent of something from side to side

X is for X-Axis • the horizontal axis in a plane coordinate system.

Y is for Y-Axis • the horizontal axis in a plane coordinate system.

Z is for Z-Axis • the horizontal axis in a plane coordinate system.
