7th Grade Unit 1 Vocab

Which definition best matches “scale”?

• An equation stating two ratios are equal.

• The number that multiplies each original length to get the scaled copy.

• A ratio that compares a length on the drawing to the actual length (e.g., “1 cm represents 2 m”).

• The real-world measurement a drawing length stands for.

Which definition best matches “actual length (actual distance)”?

• The real-world measurement that a length in the drawing stands for.

• A grid used to locate points.

• A figure made by multiplying every original length by the same number.

• A ratio comparing drawing length to actual length.

Which definition best matches “unit rate”?

• A rate with a denominator of 1 (useful for “per 1” conversions).

Which definition best matches “enlargement”?

• The rule that areas change by k^2.

• A scaled copy with scale factor between 0 and 1.

• The ratio comparing a drawing to reality.

• A scaled copy with scale factor greater than 1 (image is larger).

CCSS.8.G.A.3

Which definition best matches “reduction”?

• A scaled copy that preserves area exactly.

• A scaled copy with scale factor between 0 and 1 (image is smaller).

• A drawing with a stated scale like “1 cm represents 2 m.”

• The reciprocal of a fraction.

Which definition best matches “perimeter”?

• A rate per 1 used for conversions.

• The rule that areas change by k^2 when lengths change by k.

• The total distance around a figure; in a scaled copy, it changes by the same scale factor as the side lengths.

• The number of square units covering a region.

Which definition best matches “area scale factor”?

• When lengths are multiplied by k, areas are multiplied by k^2.

• When lengths are multiplied by k, perimeters are multiplied by k^2.

• A ratio comparing drawing length to actual length.

• The sum of all side lengths.

Which definition best matches “dimension”?

• The real-world length a drawing represents.

• A coordinate grid for locating points.

• A figure made by scaling every length the same way.

• A measurable length such as width, height, or depth used to describe size.
