X-axis

the horizontal number lin eon the coordinate grid

Y-axis

the vertical number line on the coordinate grid

origin

the point where the x-axis and the y-axis cross

quadrant

the four regions on the coordinate grid

coordinates are values in a…

ordered pair

Vertex

a point where two sides of a figure meet

the plural of vertex is

vertices

the movement of a geometric figure is called a

transformation

translation

a slide along a straight line

reflection

a mirror image

a turn about a fixed point is called a

rotation

to approximate an answer is to

estimate

Overestimating is when

the estimate is larger than the actual answer

Underestimating is when

estimating a number that’s smaller than the actual answer

How does adding a zero after the decimal point change the value? For example, 2.3 and 2.30

It does not change the value. 2.3 is worth the same amount as 2.30

What does the symbol ~ mean?

Approximately

What is the order of operations?

BEDMAS (Brackets) (Exponents) (Division) (Multiplication) (Addition) (Subtraction)

Another word for brackets is

parentheses

lines in the same plane that never cross or intersect are considered

parallel

Lines that intersect at 90 degrees are called

perpendicular

How are perpendicular lines marked?

with a square in the corner

a line that divides a line segment in half and is at right angles

a perpendicular bisector

an angle that is less than 90 degrees is called an

acute angle

the line that divides an angle into two equal parts

angle bisector

an angle that is greater than 90 degrees is called

obtuse

a side of a two dimensional closed figure is called the

base

the perpendicular distance from the base to the oppositte side

height

‘h’ is the symbol for

height

what does percent mean?

out of 100

a decimal number with a digit or group of digits that repeats forever is called a

repeating decimal

a decimal number in which the digits stop

terminating decimal

probability

the likelihood or chance of an event occuring

the equation for probability is

favourable outcomes / possible outcomes

outcome

one possibility result of a probability experiment

favourable outcome

a successful result in a probability experiment

sample space

all possible outcomes of an experiment

tree diagrams are used to

organize outcomes

random

an event in which every outcome has an equal chance of occuring

experimental probability

the probability of an event occuring based on experimental results

the expected probability of an event occurring is called the

theoretical probability

quotient

the result of a division question

common factor

a number that two or more numbers are divisible by

what is a common factor of 8 and 12?
