Review Practice Questions for Scale drawing Test

Front

What is a scale drawing?

Back

A scale drawing is a representation of an object or area that is proportionally reduced or enlarged to fit a specific size, maintaining the same ratios as the original.

Front

What does the term 'scale factor' mean?

Back

The scale factor is the ratio of the length in a scale drawing to the corresponding length in the original object. It indicates how much the drawing is enlarged or reduced.

Front

If a scale factor is 2, what does that mean?

Back

It means that the dimensions of the scale drawing are twice as large as the dimensions of the original object.

Front

How do you find the length of a side in a scaled copy?

Back

To find the length of a side in a scaled copy, multiply the original length by the scale factor.

Front

What is the relationship between corresponding sides in similar figures?

Back

In similar figures, the lengths of corresponding sides are proportional to each other.

Front

If 1/4 inch on a map represents 30 miles, how many miles does 1 inch represent?

Back

1 inch represents 120 miles.

Front

What is the formula to calculate the scale factor?

Back

Scale Factor = Length in Scale Drawing / Length in Original Object.

Front

What does it mean for two figures to be 'scaled copies'?

Back

Two figures are scaled copies if they have the same shape but different sizes, with corresponding sides in proportion.

Front

How can you determine if two figures are similar?

Back

Two figures are similar if their corresponding angles are equal and their corresponding sides are in proportion.

Front

What is the significance of the scale in a map?

Back
