Question

which word(s) do not mean similar? *
proportional
congruent
to scale
grow or shrink at the same rate

Explanation:

• Proportional: In geometry, if two figures are similar, their corresponding sides are proportional. So this is related to similarity.
• Congruent: Congruent figures have the same shape and size. Similar figures have the same shape but not necessarily the same size. So congruent is not the same as similar.
• To Scale: Similar figures are to - scale (i.e., one can be obtained from the other by a scaling factor).
• Grow or shrink at the same rate: This is equivalent to a scaling transformation, which is a property of similar figures.

Answer:

Congruent
