polygons
This 3-sided polygon has interior angles that always add up to 180 degrees.
triangle
In the linear equation (x + 5 = 12), (x) is equal to this number
7
In the acronym BODMAS, the letter "B" stands for this mathematical grouping symbol.
brackets
This semi-circular geometric tool is typically used by students to measure or draw angles in degrees.
protractor
The absolute probability of a completely impossible event occurring is mathematically represented by this number.
0
A regular polygon with four equal sides and four right angles.
square
In algebra, a letter or symbol that represents an unknown or changing number is called this.
variable
According to the order of operations, this is the correct answer to the expression (10 - 2 x 4).
2
An angle that measures exactly 90 degrees is known by this specific mathematical name.
right angle
If you flip a perfectly fair coin, this is the fractional probability that it will land facing heads.
1/2
This is the specific geometric name for an 8-sided polygon, famously shaped like a standard stop sign.
octagon
To find the value of (y) in the equation (3y = 27), you must perform this operation on both sides.
division (or dividing by 3)
The final simplified value of the mathematical expression (5 + (6 \ 2) x 3)
14
Named after an ancient Greek mathematician, this theorem states that (a^2 + b^2 = c^2) for right triangles.
Pythagorean Theorem
This number represents the total sample space (total possible outcomes) when rolling a single standard six-sided die.
6
he formula (n - 2) x 180 is used to calculate the sum of these geometric features inside a polygon.
interior angles
This value represents the slope of the line given by the equation (y = -4x + 7).
-4
In BODMAS, when a problem contains both Division and Multiplication sequentially with no brackets (e.g., (12 / 3 times 2), you must solve them in this directional order.
left to right
To calculate the circumference of a circle, you must multiply its diameter by this infinite mathematical constant
pi
If a bag contains 3 red marbles and 7 blue marbles, this is the percentage probability of randomly pulling out a red marble.
30%
A polygon is given this classification if it has at least one interior angle greater than 180 degrees, making it "cave inward."
concave polygon
This popular algebraic mnemonic method uses an acronym to remind students how to multiply two binomials together.
foil
The final simplified value of this multi-operation expression: (4^2 - (3 + 1) x 2)
8
Two lines are given this geometric designation if they intersect one another at a perfect 90-degree angle.
perpendicular lines
Two mathematical events are called this if the outcome of the first event has absolutely no effect on the probability of the second event occurring.
independent events
