The ABC's of Algebra & GeometryBy Samantha Pitta - May 2014
A is for Angle
• An Angle is the figure formed by two rays, called sides, that share the same endpoint.
B is for Biased Sample
• A Biased Sample is a sample that is NOT representational of the population.
C is for Circumference
• Circumference is the distance around a circle.
D is for Dividend
• The dividend is the number to be divided.
E is for Equilateral Triangle
• An equilateral triangle is a triangle in which all 3 sides have the same length.

20 IN.
F is for Fraction
• A fraction is number that shows a part of a set, a point on a number line, a part of a whole, a quotient, or a ratio.
H is for Hypotenuse
• Hypotenuse is the side opposite of the right angle in a right triangle.
I is for Isoceles Triangle
• An Isoceles Triangle is a triangle that has at least 2 equal sides in length.
J is for Justify
• To Justify simply means to show how you can change the way a problem is set up.
K is for Kite
• A Kite is a quadrilateral with two pairs of adjacent sides that are congroent, the diagonals of the kite are perpendicular.
L is for Least Common Multiple
• The Least Common Multiple is the least non-zero number that is a multiple of two or more non-zero given numbers.
M is for Mode
• Mode is the data values that occur most often in a set of data; data may have 0,1,or many modes,
N is for Number Line
• A Number Line is a line on which each point represents a number.
O is for Order of Operations
• The Order of Operations is the order in which operations must be computed when more than one operation is involved.

P is for Pi
Pi is the ratio of a circle to its diameter. Pi is written π and is a trancendental number.
Q is for Quadrants
• Quadrants are one of the four regions into which the coordinate axes seperate the coordinate plane.
R is for Rational Number
• A Rational Number is any number that can be expressed as a ratio where a and b are intergers and b is non-zero.
S is for Surface Area
• Surface Area is the sum of the areas of all surfaces of a three-dimensional figure.
T is for Transformation (Geometric)
• Transformation is a movement or change of a figure, such as a translation, reflection, rotation, or dialation.
U is for Unit Rate
• The Unit Rate is a rate that is a denominator of one unit.
V is for Vertex
• Vertex is the common endpoint of the two rays or segments that form an angle less than 80 degrees.
W is for Whole Numbers
• Whole Numbers are 0 and the counting numbers.
X is for X-Axis
• The X-Axis is the horizontal axis on a coordinate plane.
Y is for Y-Axis
• The Y-Axis is the vertical axis on a coordinate plane.
Z is for Zero Product Property
• Zero Product Property is for all numbers a and b, if ab=0 then either a=0 or b=0 or both a and b equal 0.
