A transformation that turns a figure about a fixed point
rotation
Which axis is vertical?
the y-axis
When writing the rule for a translation, one must include how many ________ you move the object.
units
What is the line called that you flip an object over?
Mirror line/ Reflection line
Which two directions can you rotate an object?
clockwise and counter-clockwise
What is a transformation where each point in a shape appears in an equal distance on the opposite side of the given line
reflection
The point (3,-6) is in which quadrant?
quadrant 4
2
THREE PLACES TO THE LEFT.
TWO PLACES UP.
Which line states that for every Y value the X value is the same.
Y=X LINE
What three things must you include when writing a rule about rotation?
degrees, direction, and rotation point
Moving a shape so that it is in a different position, but still has the same size, area, angles and line lengths.
transformation
The line y=5 is vertical or horizontal?
horizontal
The top value of a vector determines if the object moves from what to what?
left to right
the line y=0 is which axis
x axis
The corners of a rectangle have coordinates (3, 2), (7, 2), (7, 5) and (3, 5). The rectangle is to be rotated through 90 ° clockwise about the origin.
What are the new points for the rectangle
(2,-3), (2, -7), (5,-7), (5, -3)
Same shape, but different size means __________. Same shape, same size means ______________.
similar and congruent
This is defined by two perpendicular number lines: the x-axis, which is horizontal, and the y-axis, which is vertical. Using these axes, we can describe any point in the plane using an ordered pair of numbers.
We also do all forms of transformation on this plane
Cartesian Plane
What is the name of the online software used in class to translate objects
Geogebra
If a triangle has points (1,1) (4,1) (2,3) which line will it be reflected in if the image would be (1,-1) (2,-3) (4,-1)
y=0
A rectangle has corners at the points A (2, 4), B (6, 4), C (6, 6) and D (2, 6).
If it is rotated clockwise through 180° about the point (0, 0). Which quadrant will it fall into
Quadrant 3
