Transformations
The original shape before you perform the transformation
Preimage
when a number is (larger) than the other number
Greater than
A (symbol) or (letter) that represents an unknown number
Variable
This is the Pythagorean Theorem
a2 + b2 = c2
My angles equal 90 degrees
Complementary
To move or slide a shape on a coordinate grid
Translate
When a number is (smaller) than the other number
Less than
a mathematical statement that shows (two) amounts are (equal).
Equation
You do this to find the Percent of Change.
new-old divided by old times 100
My angles equal 180 degrees
Supplementary
A set of values that show an exact position.
Coordinates
When a number is (larger), but also (the same as) the other number.
Greater than or equal to
To replace a variable with a given number in an equation or inequality
Substitute
To change a percent to a number, you must do this
divide by 100
My angles are opposite and equal
Vertical
A point where two or more line segments meet. A corner.
Vertex
A mathematical statement showing one amount is (greater) than or (less) than another.
Inequality
Perform mathematical operations to get the variable (alone) or apart from others
Isolate the Variable
This is a way we remember the Order of Operations
GEMDAS
My angles share a vertex and one side.
Adjacent
The result of performing a transformation on a shape, the new shape
Image
The group of (numbers) that can satisfy an equation
Solution Set
A group of numbers, symbols, and variables that express an operation or series of operations
Algebraic Expression
Stragety we use to solve an equation or inequality
