4. MCC8.G.1: Verify experimentally the
properties of rotations, reflections, and
translations:
a. Lines are taken to lines, and line segments
to line segments of the same length.
b. Angles are taken to angles of the same
measure.
c. Parallel lines are taken to parallel lines.
5. Transformations: the mapping, or movement,
of all the points of a figure in a plane
according to a common operation.
Translation: a transformation that “slides”
each point of a figure the same distance in
the same direction.
6. What does a translation allow us to do to a
polygon?
Yes, we can “shift” the figure in any
direction, which allows us to create a
new, congruent figure.
Recall from yesterday: What is a congruent
figure?
8. Given the figure, translate the polygon 4 units
left. What are
the coordinates
of the congruent
figure?
9. Given the figure, translate the polygon 1 unit
up. What are
the coordinates
of the congruent
figure?
10. What did you notice about the new figure that
is created after the translations??
11. Using the following polygon, create a congruent
polygon using the given translations.
1. For each vertex of the given polygon ABCD,
using the form (x, y), what are the coordinates?
12. 2. Translate the original polygon left 3 units.
What are coordinates of the congruent
figure?
3. Translate the original polygon up 4 units.
What are the coordinates of the congruent
figure?
13. Translate the original polygon right 2 units and
down 5 units. What are the coordinates of
the congruent figure?
Discuss the Differentiation:
Discuss the figure you created and the
translations with a partner. Check each
other’s work for accuracy. Ask questions as
necessary.
