Transformations
Define the following:
Reflection:
Line Symmetry:
Dilation:
Rotation:
Translation:
Point Symmetry:
For numbers 1-4, use the triangle with coordinates A(2,1), B(3,1), and C(5,3).
1. Reflect the triangle over the y-axis. Label the coordinates A
¢
B
¢
C
¢
2. Reflect the triangle over the line y = x. Label the coordinates A
¢
(B
¢
(C
¢
(
3. Dilate the triangle D-3. Label the triangle A
¢
((B
¢
((C
¢
((
4. Translate the triangle with a translation of T-3,5. Label the triangle A
¢
(((B

5. If a tranlation maps (3,1) onto (4,-2), what is the image of (4,-1) under the same translation.
6. Draw all lines of symmetry for the following:
a)
M
b)
H
c) d)
7. Transformation Dk maps (-3,6) to (-1,2). What is the value of k? What is the image of (-6,-12) under the same transformation?
