Dilations
Daily Quadruple!!!!
A(1,1), B(1,3), C(3,1); k-factor is 3
A'(3, 3), B'(3, 9), C'(9, 3)?
Horizontal axis direction
Left to Right or Right to Left
Translate: (1, 3) one unit to the left (x-1)
(0, 3)
The change in the sequence 1, 2, 3, 4, 5...
The change is increasing by 1
Daily Double!!!!!!!!!!!!!!!!
Name the 4 transformations
The 4 transformations are, Reflections, Translations, Rotations, and Dilations
Daily Double!!!!!!!!!!!!!!!!
What is the k-factor used?
A(-4,-2), B(-1,4), C(12, 8);
A'(-1,-0.5), B'(-0.5, 1), C'(3,2)
The k-factor used is k=1/4 or 0.25
Daily Double!!!!!!!!!
Y-axis runs in which directions?
up and down
What is the ordered pair for the point of origin?
The ordered pair for the point of origin is (0,0)
What is the Square Root of 100? Explain why?
The Square root of 100 is 10
because 10 x 10 = 100
The commons description of Dilations.
Dilations make figures larger or smaller
What is the k-factor for an enlargement?
What is the k-factor for a reduction?
The k-factor for an enlargement is K>1
The k-factor for a reduction is K< 1
Daily Double!!!!!!!!!!!!!!!!
The location of (-3, 2) if it is reflected over the horizontal axis
The location after a horizontal reflection will be at
(-3, -2)
Name the translation:
(x+2, y - 6)
The translation is 2 right and 6 down
Daily Double!!!!!!!!!!!!!!!!
The change in the sequence 3, 0, -3, -6, -9...
What is -3?
The commons description of Reflections.
What is "flip?"
Name the types of Dilations
The two types of Dilations are
enlargement and reduction
What are reflections key words?
The reflection key words are FLIP and MIRROR IMAGE
Daily Double!!!!!!!!!!!!!!!!
Translate: (0, -2)--right 7
The prime coordinate will be (7, -2)?
Explain radius and diameter in your own words
Radius is half of the diameter or diameter is twice the radius
What is the common description of Translations?
Translations SLIDES a figure into a different part of the coordinate plane
Dilate using k-factor 0.5
M(3, -12) A(2, 8) T(4, 1) H(-10, -2)
After applying a k-factor of 0.5 the coordinates are: M(1.5, -6) A(1, 4) T(2, 0.5) H(-5, -1)
Can a reflection be similar to a rotation?
No, because reflection are flips and rotations are turns
Name the Translation: (x - 1, y - 5)
What is 1 left, 5 down?
Expressions are mathematical sentences
Equations are made up of 2 mathematical sentences that are equal to each other
How many Quadrants are on a Coordinate Plane?
