Rigid Transformation
The line that we use in reflections.
What is a line of reflection?
Congruent figures have these things that stay the same.
When the scale factor of an object is less than 1.
What is a reduction?
Similar images have this that stays the same.
What is shape?
The name of Mrs. Verkler's dog.
What is Ralph?
What we refer to as the direction and distance of a rotation.
What is clockwise/counterclockwise and degrees?
Congruent figures can undergo this type of transformation.
What is rigid transformation?
The scale factor used for this dilation: (2,1) dilated to (4,2)
What is 2?
The ratio of the images is 2:5, if one image has a side at x, the corresponding side is at 15.
What is 6?
The things we need to have ready at the beginning of class.
What is our warm up sheet and homework?
The triangle with it is rotated 90 degrees clockwise about the origin with coordinates (1,-1), (1,-4), (2,-4).
What is a triangle with coordinates at (1,1), (4,1), and (4,2)?
When you start with (6,0), (-6,-3) and (0,6) with a scale factor of 1/3 this is what you end up with.
What is a triangle with coordinates at (2,0), (-2,-1) and (0,2)?
What is YZ?
What it means when you get a 4 on a question.
What is I am an expert?
Starting with a triangle with points (-3,-1), (1,-3), and (-4,-4) translated 2 units right and 3 units up.
What is (-1,2), (3,0), and (-2,-1) as the new coordinates of my triangle?
When two images are congruent but are on opposite sides of the x-axis and one is a flipped image of the other, that transformation is.
What is a reflection?
It is the point where the dilation occurs.
What is the center of dilation?
The transformations that can occur for images to be similar.
What is dilation?
Where you need to be to eat your snack.
What is the picnic tables?
When I reflect the triangle (1,-1), (4,3), (2,-4) with a line of reflection on the y-axis.
What is a new triangle at (-1,-1), (-4,3), (-2,4)?
Images that have a scale factor greater than 1 form this type of change.
What is an enlargement?
When you have a rectangle that has a length of 10 and height of 6, using a scale factor of 1/2 turns it into this.
What is a rectangle with a length of 5 and a height of 3?
