Unit 1: polynomials

100

3x(9x² − 4x - 15)

             27x³- 12x² - 45x

          (3 x 9 = 27,3 x 4 = 12 15 x 3 = 45)

          (x x x² = x³ , x times x is x², x times a number is Nx)

200

What is secondary name of this polynomial?

                                X² + 9x - 4x + 8

     Polynomial 

      4 separate terms = polynomial.

300

     What is the degree of this number?

                         4x³

Cubic

x³ = cubic since x³= x times itself 3 times

400

What would you call this polynomial 

        (6x³ + 4x² + 2x + 7)

Cubic Polynomial

Highest degree = 3, 4 separate terms

500

(4x³- 9x² + 3x) -(-7x² + 4x -6)

    4x³ - 2x² - x -6

4x³ (-9x² 

Unit 2: Geometric Notation

100

 Which shape ISN'T a quadrilateral?

 A( Rectangle

B( Triangle

C( Square

D( Trapezoid

 B) Triangle

Triangles have 3 sides,while quadrilaterals have 4.

200

Which quadrilateral has four right angles,and 2 congruent sides

Rectangles

(Squares have all congruent sides.)

300

<8 and <9 =180. What type of pair are these angles?

Linear pair

180^o = linear angle, therefore 2 angles that make 180 degrees are a linear pair.

400

If <5 and <6 = 90^o , what kind of angle are 5&6?

Supplementary

Supplementary angles add up to 90 degrees.

500

What does CPTPC mean

Corresponding Parts of Congruent Triangles are Congruent

Unit 3: Transformations

100

If I translate point Q (6,7) 5 units up and 3 units right, where will point Q' be?

                      (9,12)

(3+6=9,7+5=12)

200

If I dilate point W,(12,14) by 1/2,Where will point W' be?

                                   (6,7)

     (12/2 = 6,14/2= 7)

300

If I rotate N(9,7) 180 degrees, Where will point N' be?

(-9,-7)

180 degrees= (-x,-y)

400

If I reflect point y (3,4) over the x-axis, where will point x' be?

 (3,-4)

(x,-y)

500

If I reflect point E(5,3) over the y axis,where will E' be?

 (-5,3)

(-x,y)

Unit 4:Similarity

100

X is at (3,4),Y is at (9,8),and Z is at (4,2)

X' is at (9,12),Y' is at (27,32),and Z is at (12,6)

Are XYZ and X'Y'Z' similar?

No 

Everything else is multiplied by 3, while 8 is multiplied by 4.

200

If 2 shapes have the same length and angles,are they similar?

 No

They are similar

300

which statement shows similarity

A)HL

B)AA

C)SSA

B

Angle angle is similarity

400

If 2 shapes are the same size and different lengths,are they similar?

No

500

If 2 shapes have the same length and size,are they similar?

No

They are congruent.
