Scale Factor and Scale Drawings Review

Front

What is a scale factor?

Back

A scale factor is a number that scales, or multiplies, some quantity. In geometry, it is the ratio of the lengths of two corresponding sides of two similar figures.

How do you calculate the scale factor between two similar shapes?

Back

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

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 while maintaining the same shape.

Front

If a scale drawing has a scale of 1 inch = 10 feet, how many feet does 3 inches represent?

Back

3 inches represents 30 feet.

Front

What is the purpose of using scale factors in real-life applications?

Back

Scale factors are used to create accurate representations of objects or distances that are too large or too small to be drawn or measured directly.

Front

How do you convert a scale drawing measurement to actual size?

Back

To convert a scale drawing measurement to actual size, multiply the measurement by the scale factor.

Front

What is the relationship between scale factors and ratios?

Back

Scale factors are a type of ratio that compares the dimensions of two similar figures.

Front

In a scale drawing, if the scale is 1:50, what does this mean?

Back

This means that 1 unit on the drawing represents 50 units in reality.

Front

How can you find the actual distance between two points on a map using the scale?

Back

To find the actual distance, measure the distance on the map and multiply it by the scale factor.

Front

What is the significance of maintaining the same proportions in scale drawings?

Back

Maintaining the same proportions ensures that the scale drawing accurately represents the dimensions and relationships of the original object.
