Representation of a Situation Cartesian Plane

Algebra BEDMAS Integers Similar Terms Monomials Polynomials Variable (a letter to represent the variable) Constant (a number that does not vary)  Independent variable (side length, etc)  Dependent variable (perimeter)

Monomials

Adding and Subtracting Monomials

Multiplying Monomials

Dividing Monomials

Dilations and similar figures Dilation = multiply (gets bigger) Divide if it smaller Similar figures  Must have same angles  Must have same shape  Must have same proportion

Polygons Perimeter of a regular polygon  P = n X c (n is the number of sides, c is the side length) Area of a regular polygon  A = p X a / 2 (p is the perimeter, a is the apothem)

Interior angle  Sum of interior angles = (number of sides – 2) X 180 degrees  Interior angle = sum of interior angles / # of sides Exterior angle  Exterior angle = sum of exterior angles / # of sides Apothem  Apothem = 2 X area / perimeter

Regular polygon Number of sides Number of diagonals from a given vertex Sum of the interior angles Measure of one interior angle Pentagon Hexagon Octagon Decagon Polygonnn - 3(n – 2) X 180(n – 2) X 180 / n

Circle Area of a circle Perimeter (circumference) of a circle

Solids Use your formula sheet

Probability Basic counting rule  2 steps  A x B  3 steps  A x B x C Probability of an outcome  P(a) = # of favourable cases / # of possible cases Probability of an event in an equally probable space  P(a) = # of favourable outcome to occur / # possible outcomes in the experiment
