DO-NOW #56: Answer the following questions:
1) Define the following:
a. Dilation:
b. Scale factor:
c. Similar figures:
Topic: Transformations
Main Idea: Similarity and Transformations
Aim:
RECALL
On graph paper, plot the endpoints J(1, 5) and
K(4, 1) and connect them. Measure JK .
On the same graph paper, double the x- and ycoordinates of the previous endpoints and connect
them. Labe the new segment J ' K ' and measure it.
NOTES
Suppose you draw a line segment on a coordinate grid,
then multiply the x- and y- coordinates of the endpoints
by ½. What conjecture can you make about the length
of the new segment?
STATEMENT: Two figures are similar if the second can be obtained from the first by a
sequence of transformations and dilations.
STATEMENT:
Drill: Answer the following questions. Show work.
