PSA6PV2 - Practice Problems---7.1 Lesson 2: Corresponding Parts and Scale Factors (7.G.A.1)
Part A)

The smaller H-shaped polygon is a scaled copy of the larger.

Show one pair of corresponding points between the two polygons. Then, show two pairs of corresponding sides between the polygons.

Consider using colored pencils to highlight corresponding parts or labeling some of the vertices.

Draw your points and sides on paper, take a picture, and upload it using the image upload icon

If you do not have the ability to upload an image of your work type "drawing is on paper."

Part B)

What scale factor takes the original polygon to its smaller copy?

Type your answer below as a number (example: 5, 3.1, 4 1/2, or 3/2):
Part C)

Explain.

Figure B is a scaled copy of Figure A. Select all of the statements that must be true.

Select all that apply:
