1. The ABC's of Algebra &
GeometryBy Samantha Pitta - May 2014

2. A is for Angle
•
An Angle is the figure formed by
two rays, called sides, that share
the same endpoint.

3. B is for Biased Sample
•
A Biased Sample is a sample that is NOT
representational of the population.

4. C is for Circumference
•
Circumference is the distance around a circle.

5. D is for Dividend
•
The dividend is the number to be divided.

6. E is for Equilateral Triangle
•
An equilateral triangle is a triangle
in which all 3 sides have the same
length.
20 IN.20 IN.20 IN.20 IN. 20 IN.
20 IN.

7. 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.

8. H is for Hypotenuse
•
Hypotenuse is the side opposite of the right
angle in a right triangle.

9. I is for Isoceles Triangle
•
An Isoceles Triangle is a triangle
that has at least 2 equal sides in
length.

10. J is for Justify
•
To Justify simply means to show how you can
change the way a problem is set up.

11. 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.

12. 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.

13. 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,

14. N is for Number Line
•
A Number Line is a line on which each point
represents a number.

15. 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.
Way to remember:
"Please Excuse My Dear Aunt Sally"
PEMDAS
Parentheses
Exponents
Multiply
Divide
Addition
Subtraction

16. P is for Pi
Pi is the ratio of a circle to its diameter. Pi is
written π and is a trancendental number.

17. Q is for Quadrants
•
Quadrants are one of the four
regions into which the coordinate
axes seperate the coordinate
plane.

18. 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.

19. S is for Surface Area
•
Surface Area is the sum of the areas of all
surfaces of a three-dimensional figure.

20. T is for Transformation
(Geometric)
•
Transformation is a movement or change of a
figure, such as a translation, reflection,
rotation, or dialation.

21. U is for Unit Rate
•
The Unit Rate is a rate that is a
denominator of one unit.

22. V is for Vertex
•
Vertex is the common endpoint of the two
rays or segments that form an angle less than
80 degrees.

23. W is for Whole Numbers
•
Whole Numbers are 0 and the counting
numbers.

24. X is for X-Axis
•
The X-Axis is the horizontal axis on a
coordinate plane.

25. Y is for Y-Axis
•
The Y-Axis is the vertical axis on a
coordinate plane.

26. 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.
