Define Translation
When you slide a figure or point.
100
Define Reflection.
When you flip or make a mirror image of a figure or point.
100
Define Rotation
When you turn a figure or point. (can be clockwise or counterclockwise)
100
Define Dilation.
When you enlarge or shrink a figure or point by multiplying it a scale factor.
100
What transformation(s) keep the object the same size and shape?
translation, rotation, and reflection
200
Describe the translation:
Slide the figure or point 5 units to the left and 3 units up.
200
What is the rule for reflecting over the y-axis
Flip left or right.
200
What are the three types of rotations we performed in this class
90 degrees clockwise
90 degrees counterclockwise
180 degrees
200
What is the algebraic rule when dilating a point with the scale factor 4.
times all points by 4
200
What transformation(s) changes the size of the shape?
Dilation
300
B' (5,4)
C' (5,7)
D' (7,10)
300
Reflection over y-axis
300
What is the rotation seen on this graph?
90 degrees counterclockwise
300
Triangle ABC is being dilated by scale factor 1/4. Is the triangle enlarging or shrinking? How do you know?
Shrinking. The scale factor is less than 1, so that is why the triangle is shrinking.
300
What transformation has occured?
90 degrees clockwise
