2. ANGLE OF ROTATIONSymmetry & SA
Angle of rotation is the shortest angle, a shape can be turned around
the centre of the shape. For example you can turn a rectangle four
times so you divide 360 degrees by 4 to get 90 as your answer.

3. BEDMAS
Brackets
Exponents
Division
Multiplication
Adding
Subtracting
You use bedmas for solving any equations that include
polynomials and rational numbers.You must follow these set
of acronyms, where you complete the letters of bedmas
from left to right.
Example:

4. COEFFICIENT
It is used as the first number in the equation, but is a number
used to multiply the variable.The picture below shows an
example of an equation including a coefficient.
Polynomials & Exponents

5. DISTRIBUTIVE PROPERTY
You use the numbers on the outside of the brackets to multiply
what is inside of the brackets. Meaning you must use the
isolated number to solve your equation before anything else.
Polynomials & Linear Equations
An example of Distributive property: 2(3n + 1)

6. EXPONENT
An exponent tells how many times you need to multiply the
base to itself. In this case it would be 8 x 8.
Division rule: If the bases are the same you subtract the exponents
Multiplication rule: If the bases are the same you add the exponents

7. FRACTIONS
A fraction is a number below1or not whole.There are many
different versions of fractions such as, mixed fractions, improper
fractions, etc.You can also turn fractions into decimals. Fractions
are used in exponents polynomials, and more.
Fractions into numbers

8. GREATER THAN
A symbol that indicates which of two numbers have the same
or different value.All of the signs and examples of inequality
below.

9. HYPOTENUSE
Circle Geometry
A hypotenuse is apart of right triangles
which insists of two legs and a hypotenuse.
The opposite side of the right angle, also
known as the longest side is the hypotenuse.
The hypotenuse gets used in Pythagorean
theorem.

10. ISOSCELES TRIANGLE
Circle Geometry
A isosceles triangle is a triangle with two sides that have the
same length. Meaning the hypotenuse will have a different
length.

11. JUSTIFY
Justifying is showing the steps and work you did to get to come up with
your answer. This is very important to do otherwise nobody will know
how you came up with your answer and your work will be questionable.
All units!!!

12. KILOMETRE
A kilometre is a unit of measurement in the metric system.
Kilometres can be squared and it is used in many units.
ST Symbol: Km

13. LINE SYMMETRY
If you can reflect a figure (like a mirror) or fold it so both side
match, then the image has "line symmetry". Here are examples
of shapes with multiple lines of symmetry.
Symmetry & SA

14. MONOMIAL
A monomial is one polynomial in a term in an equation.
Different examples of a monomial are things like a simple
number, a variable or an expression.
Polynomials

15. NUMBER LINE
A number line is an organized line where numbers are
placed from least to greatest.These were used to order
rational numbers and integers.

16. ORDER OF OPERATIONS
The order of operations refers to "BEDMAS" and starting
from "B" and ending right at "S".These orders are used when
you're solving an equation of a polynomial.

17. PYTHAGOREAN THEOREM
A² + B²= C²
Pythagoreans theorem is a formula that allows you to find sides of
right angle triangles.If you figure out two sides of a right triangle, you
can find the third.

18. QUADRANTS
Symmetry & SA
The graph in the picture gets
divided into four different
equal sectors.The graph is
divided up into X,Y, -X, -Y

19. RADIUSCircle Geometry
A Radius is a line from the centre
of the circle to the perimeter. It is
half of the diameter of the circle.
It is used to find a right angle
with a tangent.
Also a radius is used in many formulas to
find areas, for example:
Pi x r2 x h

20. SCALE FACTORSimilarity / Scales
A number that is used to multiply all dimensions so the
object either gets bigger or smaller.
Image measurement
Actual measurement
If the scale factor gets
decreased in the new image
than it is a reduction.
If the scale factor gets increased
in the new image than it is
called an Enlargement

21. TANGENT LINES
Circle geometry
A line that touches the circumference on the circle.The
tangent line gives you a right angle with the radius, when it is
perpendicular.

22. UNLIKE TERMS
Polynomials & Inequalities
In terms, if there are any with different variables, or exponents it
makes it an "unlike term". If it has a different coefficient it is not
considered an unlike term. If you have unlike terms you cannot
subtract or add them.

23. VARIABLES
A variable is a letter or symbol which has an
unknown quantity.AVariable will replace an
unknown number.
Linear relations & polynomials

24. WHOLE NUMBERS
A number that is not a fraction or decimal (rational
numbers). Negatives are also not whole numbers,
because negatives are "wholes".

25. X AXIS
The x axis is the horizontal line on a graph or chart that
crosses through the middle. It is used as a tool to find
coordinates.You use the x axis to locate the coordinate before
the y axis.

26. Y AXIS
The y axis is the vertical line on a graph or charts that crosses
through the centre.When you find coordinates the y axis is
found after the x axis.

27. ZERO PAIRSRational Numbers & Inequalities
They are a pair of numbers with a positive and negative which
equal to zero. Zero pairs is a helpful method used to cancel out
numbers and terms.
