Pre-Chapter 1 Review
What is an integer?
Positive and negative numbers (including zero)
What are like terms?
numbers or letters that are the SAME and should be combined
What is a translation?
A transformation when all the points of a shape "slide" over, up or down
angles that are in the same position on different lines
Name two or three words that mean ADDITION.
all together,add,combine,plus, both, sum, increase, more, save, receive,
top number in a fraction - how many pieces are colored in or selected
What is a variable?
LETTER USED IN MATH - used to hold the spot of a number we don't know yet
What is a reflection?
A transformation when all points of a shape "flip" over a mirror or line of reflection
What are supplementary angles?
two angles that add up to 180 degrees
difference, take away, how many more, spend, remain, less, fewer, minus, decrease, less
What is a denominator?
bottom number in a fraction - how many pieces the shape is cut into
What is the distributive property?
a property when two or more terms INSIDE a set of parentheses are multiplied by a term OUTSIDE the parentheses, such as a(b + c) = ab + ac
What is a rotation?
A transformation when all points of a shape "turn" around a point of rotation
Alternate Interior Angles
angles that are on the inside of 2 parallel lines and on opposite sides of a transversal
List 2-3 words that mean MULTIPLICATION.
Multiply, Double, Product, Times, Twice, Each, Quadruple, Triple,
What is a mixed number?
a number made up of a whole number and a fraction of "leftovers"
What is a mathematical expression?
math sentence that DOES NOT have an equal sign
What is a dilation?
A transformation that changes the size of an object, but not the shape.
What are alternate exterior angles?
Angles that are on the outside a pair of lines and on opposite sides of a transversal
List 2-3 words that mean DIVISION.
value, quotient, divided by, as much, split, separated, equal parts, share.
What is an improper fraction?
a fraction whose numerator is larger than the denominator (more than 1 full shape is colored in)
What is a mathematical equation?
math sentence that DOES have an equal sign
What is a rigid motion?
A transformation that creates congruent shapes by preserving the side lengths and angle measures of a shape
Examples: translation, rotation, reflection
The interior angles of a triangle add up to _ degrees.
Fill in the blank.
180 degrees
What does equivalent or congruent mean?
the same size AND shape
