Name the 3 types of transformations
What are translations, rotations, and reflections
100
Describe what congruence is
When two figures are the same shape and size
100
What type of transformation doesn't change the shape and size of a given figure
What is a rigid transformation?
100
On two congruent shapes, what 3 things correspond?
Point, side lengths, angles
200
Describe how to get from ABCD to A'B'C'D'
Reflect over line M
200
Determine if these are congruent. If yes, describe a sequence of transformations.
Yes. Refelctions, translation
200
Where are the coordinates of D', E', and F' after a reflection over the y-axis
D' (3, 3)
E' (-5, 0)
F' (-2, -2)
200
Determine if these are congruent or not. If yes, explain why, if no, expalin why.
No, these are not the same shape.
300
Do all the following transformations.
Answers on seperate sheet

Determine if these two figures are congruent. If yes, explain using only two transformations
90 degree rotation about (0,)
translate 1 down
300
Selecat all the correct translations
1, 2, 3
300
Determine if the following shapes are congruent: If yes, explain a sequence of transformations. If no, explain why.
Yes, Rotation, translation
400
Find the coordinates for the following points:
Red: What are the coordinates after a translation of 5 units to the right and 4 units down
Blue: What are the coordinates after a 90-degree clockwise rotation around the origin (0,0)
Green: What are the coordinates after a reflection over the x-axis)
Red: (-1, 2)
Blue: (-6, 6)
Green: (4, -4)
400
These are congruent: Explain whether or not Line AB and A'B' are congruent.
Congruent shapes have corresponding side lengths so because they are congruent, line AB and A'B' are congruent.
400
For the following: Draw a line of reflection so A'B'C' is the image of ABC
y= 1
400
Determine if the following are congruent. If yes, explain using a sequence. If no, explain why.
No, these two figures are the same shape but they are not the same size, Line GH is 4 units where CD is only 3.

Complete the following transformations:
Draw B, the image of A after a reflection over the x-axis.
Draw C, the image of B, by translating (X– 7, Y + 4)
Draw D, the image of C, by rotating Shape B 90 counterclockwise around the origin.
See image.

Complete the following Directions:
Draw B, the image of A, using the y-axis as the line of reflection.
Draw C, the image of B by rotating 180 degrees clockwise around point the origin.
Draw D, the image of C, using the x-axis as the line of reflection
Draw E, the image of D, by translating (X-6, Y-5)
