1. Warm-Up How many lines of symmetry do the figures have? Draw them!
State the order and magnitude of symmetry for each figure.
Then/Now

2. Draw and identify dilations in the coordinate plane.
I will be able to….
Draw and identify dilations in the coordinate plane.
Then/Now

3. What transformations have we learned so far?
Reflections (Section 9-1)
Rotations (Section 9-3)
Translations (Section 9-2)
Dilations (Section 9-6)
…….what is a dilation?

4. What’s a dilation? A dilation is a similarity transformation that enlarges or reduces a figure proportionally with respect to a center point and a scale factor.

6. Example: Trapezoid EFGH has vertices E(–4, 2), F(–2, 4), G(4, 2) and H(–2, –4). Graph the image of EFGH after a reduction centered at the origin with a scale factor of

7. Graph the image of each polygon with the given vertices after a dilation centered at the origin with the given scale factor.
A(-2, -2), B(-1, 2), C(2,1);
scale factor of 2
2. V(0,0), W(3,3), X(6,3), Y(6, -3), Z(3, -3);
scale factor of 1/3
