Front

What does a scale of a map represent?

Back

A scale of a map represents the ratio of a distance on the map to the actual distance on the ground.

Front

If a map scale is 1 cm to 50 miles, how many miles does 7 cm represent?

Back

7 cm represents 350 miles (7 cm * 50 miles/cm).

Front

How do you convert a map distance to actual distance using a scale?

Back

To convert a map distance to actual distance, multiply the map distance by the scale factor.

Front

What is the scale factor if a triangle is reduced to half its size?

Back

The scale factor is 1/2.

Front

If a triangle has a perimeter of 30 cm, what would be the perimeter of a triangle with a scale factor of 1/3?

Back

The perimeter would be 10 cm (30 cm * 1/3).

Front

What is the relationship between the scale of two different maps of the same area?

Back

The relationship can determine how the size of features on one map compares to the other.

Front

If a map's scale is 1 cm to 25 miles, how many miles does 15 cm represent?

Back

15 cm represents 375 miles (15 cm * 25 miles/cm).

Front

What does it mean if one map is larger than another with different scales?

Back

It means that the features represented on the larger map are depicted at a greater size compared to the smaller map.

Front

How do you find the scale factor between two similar triangles?

Back

The scale factor is found by dividing the length of a side of one triangle by the corresponding side of the other triangle.

Front

What is the effect of a scale factor greater than 1 on a shape?

Back

A scale factor greater than 1 enlarges the shape.
