Scale Factor and Vocabulary

If a scale drawing shows a car length of 3 cm and the scale is 1 cm:4 ft, what is the actual car length?

• 8 feet

• 10 feet

• 12 feet

• 14 feet

What does it mean if two figures are similar?

• They have the same shape but different sizes, and their corresponding sides are in proportion.

• They have the same size and shape.

• They are identical in every way.

• They have different shapes but the same area.

How do you determine the scale factor from a scale drawing?

• Multiply the model measurement by the actual measurement.

• Add the actual measurement to the model measurement.

• Divide the actual measurement by the model measurement.

• Subtract the model measurement from the actual measurement.

What is the formula to convert model measurements to actual measurements?

• Actual Measurement = Model Measurement + Scale Factor

• Actual Measurement = Model Measurement - Scale Factor

• Actual Measurement = Model Measurement × Scale Factor

• Actual Measurement = Model Measurement / Scale Factor

What is the significance of the scale in a scale drawing?

• It determines the color scheme of the drawing.

• It provides a ratio that helps convert measurements from the drawing to actual sizes.

• It indicates the type of materials used in the drawing.

• It shows the artist's signature and date of creation.

If a model of a house is built at a scale of 1:10, what does this indicate?

• It indicates that 1 unit on the model represents 10 units in real life.

• It indicates that the model is 10 times larger than the actual house.

• It indicates that the model is 1/10th the size of the actual house.

• It indicates that the model can be used for 10 different designs.

If a model is built using a scale of 5 in:25 ft, what does this mean?

• This means that every 5 inches on the model represents 25 feet in real life.

• This means that every 5 inches on the model represents 5 feet in real life.

• This means that every 5 feet on the model represents 25 inches in real life.

• This means that every 5 inches on the model represents 50 feet in real life.

If a rectangle in a scale drawing has a length of 4 inches and the scale is 1 in:5 ft, what is the actual length?

• 15 ft

• 20 ft

• 25 ft

• 30 ft

What is the purpose of using scale drawings?

• To represent large objects in a smaller, manageable size while maintaining proportions.

• To create artistic representations without regard to size.

• To measure the exact dimensions of an object in real life.

• To simplify complex designs into basic shapes.

What is the relationship between corresponding angles in similar figures?

• Corresponding angles in similar figures are equal.

• Corresponding angles in similar figures are supplementary.

• Corresponding angles in similar figures are complementary.

• Corresponding angles in similar figures are always different.
