Lesson 02: Corresponding Parts and Scale Factors | Unit 1: Scale Drawings

Draw

Show one pair of corresponding points and two pairs of corresponding sides in the original polygon and its copy. Consider using colored pencils to highlight corresponding parts or labeling some of the vertices.

Open Ended

What scale factor takes the original polygon to its smaller copy? Explain or show your reasoning.

Draw

Zapotec people in southern Mexico make woven rugs like this one. Find a pair of figures in the design that are scaled copies. Outline the two figures.

Multiple Choice

What is the scale factor of the two figures identified as scaled copies in the woven rug made by the Zapotec people in southern Mexico?

• The scale factor is 2:1.
• The scale factor is 1:2.
• The scale factor is 3:1.
• The scale factor is not specified in the provided information.

Open Ended
