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?
4
