Scale Drawings Flashcards

A drawing that represents an object or area proportionally smaller or larger than its actual size.

The ratio of the dimensions in the scale drawing to the actual dimensions of the object or area.

A scale where 1 unit on the drawing represents 50 units in real life.

Multiply the measurement on the scale drawing by the scale factor to find the real measurement.

Divide the real measurement by the scale factor to find the measurement on the scale drawing.

Use the scale (e.g., 1 cm = 1 km) to calculate real distances by multiplying the map measurement by the scale.

When the scale factor is greater than 1, the drawing is an enlargement of the original object.

When the scale factor is less than 1, the drawing is a reduction of the original object.

Ensure that the units in the scale and the measurements are consistent (e.g., both in cm or both in m).

Use the given scale to determine real-life dimensions or distances by applying proportional reasoning.
