Scale Factor Review

Front

What is a scale in the context of maps and diagrams?

Back

A scale is a ratio that represents the relationship between a distance on a map or diagram and the actual distance it represents in the real world.

Front

If a map has a scale of 1cm : 4km, how do you calculate the distance on the map for an actual distance of 52km?

Back

To find the distance on the map, divide the actual distance by the scale factor. Here, 52km ÷ 4km/cm = 13cm.

Front

What happens to a figure when the scale factor is greater than 1?

Back

The figure gets bigger.

Front

What is the scale factor if a small shape is enlarged to a big shape that is twice its size?

Back

The scale factor is 2.

Front

What does a scale factor of less than 1 indicate about the new figure?

Back

The new figure will be a reduction of the original figure.

Front

How do you express a scale factor mathematically?

Back

A scale factor can be expressed as a ratio, such as 1:2 or 3:1, indicating the proportional relationship between two figures.

Front

What is the significance of a scale factor of 1?

Back

A scale factor of 1 means the figure remains the same size; it is neither enlarged nor reduced.

Front

In architectural design, why is scale important?

Back

Scale is important in architectural design to accurately represent the dimensions of a building or structure in relation to its actual size.

Front

How can you determine the scale factor between two similar shapes?

Back

To determine the scale factor, divide the length of a side of the larger shape by the corresponding side of the smaller shape.

What is the relationship between scale and proportion in art?

Back

In art, scale refers to the size of an object in relation to other objects, while proportion refers to the relative size of parts within a whole.
