4 3 2 1 0In addition to level 3.0 and above and beyond what was taught in class, I may: Make connection
with real-world situations
Make connection with other concepts in math
Make connection with other content areas.
I understand and use informal arguments to prove congruency and similarity using physical models, transparencies or geometry software. informally prove
similarity of triangles
Use scale factors to create and analyze dilations.
I understand congruency and similarity using physical models, transparencies or geometry software. construct
triangles Calculate
dilations with scale factors.
With help from theteacher, I have partial successwith the unit content.
Even with help, I have no success with the unit content.
Learning Goal 1 (8.G.A.3 & 4):The student will understand and use informal arguments to prove congruency and similarity using physical models, transparencies or geometry software.

Dilations make similar figures.
• Similar means same shape but different size.
• Are the following figures similar?
How can you tell that shapes are similar?

Is the dilation an enlargement or reduction from the shaded figure to the non-shaded figure.

How do you find the scale factor?• Take the second figure’s size and divide
it by the first figure’s size.
