Scale - transformations

Front

What is a scale drawing?

Back

A scale drawing is a representation of an object or area that maintains the proportions of the original but is resized to fit a specific scale.

Front

How do you determine the scale of a drawing?

Back

The scale of a drawing can be determined by comparing the dimensions of the drawing to the actual dimensions of the object or area it represents.

Front

If a drawing has a scale of 1 inch = 7 yards, how long is a 14-inch drawing in actual yards?

Back

The actual length is 14 inches * 7 yards/inch = 98 yards.

Front

What is a scale factor?

Back

The scale factor is the ratio of a length of the new figure to the corresponding length on the original figure.

Front

What happens to a figure if the scale factor is greater than one?

Back

If the scale factor is greater than one, the new figure will be an enlargement.

Front

What happens to a figure if the scale factor is less than one?

Back

If the scale factor is less than one, the new figure will be a reduction.

Front

What is a translation in geometry?

Back

A translation is a type of transformation that moves every point of a figure the same distance in the same direction.

Front

How can you identify a translation of a figure?

Back

A translation can be identified by the consistent movement of all points in the figure to a new location without changing its shape or size.

Front

What is the difference between a scale drawing and a regular drawing?

Back

A scale drawing maintains proportional relationships and is resized according to a specific scale, while a regular drawing may not maintain these proportions.

Front

What is the purpose of using scale drawings?

Back

Scale drawings are used to represent large objects or areas in a manageable size while preserving the proportions.
