Symmetrical Line – A line split between two sides of a frame. Both sides are the exact same.
Perimeter – The total length and width of an shape.
Area – The length and width multiplied together.
Volume – The measurement of the amount of space inside a solid figure (3-D figure).
Factor – (Using 6) the factor of 6 would be 1,2,3 and 6. Factors are usually a part of a number, and that the part is divisible by the number (which is 6). 3 is divisible by 6, 2 is divisible by 6, 1 is divisible by 6 and 6 is divisible by 6.
Factorials – The result of multiplying a series of descending natural numbers.
Circumference – It’s like the perimeter (only used for circle and sphere) except it has a different formula, like 2πr (2 x 3.4 or 22/7, then multiplying the radius)
Radius – Used to find the diameter of a circle, the circumference of a circle or the area of a circle.The radius is half of the diameter (basically meaning starting from the center point, it’ll only go one direction….either left or right) It is the diameter divided by 2.
Diameter – Starting from the center point of a circle, it’ll go both directions, meaning it is the radius multiplied by two… it can be used to find the radius if you divide the diameter by two.
Hypotenuse – Mainly a word used in the Pythagorus Theorem. It’s the longest side of a right side triangle.
Algebra – An equation that has unknown numbers and is substituted with letters.
Linear Equation – An equation that is set straight. (ex: 6x + 2 = 41 – 7)
Coefficient - A numerical or constant quantity placed before and multiplying the variable in an algebraic expression.
Simultaneous Equations – A set of equations containing multiple variables.
Polynomials – An expression made with constants, variables and exponents, which are combined using addition, subtraction and multiplication, but not division.
Quadratic Equation - Involving the second and no higher power of an unknown quantity or variable.
Experimental Probability – Experimenting with probability without using any equations or theories.
Theoretical Probability – Using theories and equations for probability instead of experimenting.
