Scale Factor

What are corresponding sides?

• Sides that are in the same position in different shapes.

• Sides that are equal in length regardless of shape.

• Sides that are opposite to each other in a shape.

• Sides that are adjacent to each other in a shape.

What is a scale factor?

• A number that scales or multiplies some quantity.

• A measurement of distance between two points.

• A method for calculating area.

• A type of geometric transformation.

What is the scale factor if a triangle's side lengths are 3 cm and 9 cm?

• 1

• 2

• 3

• 4

If a shape is reduced by a scale factor of 0.25, what is the new size compared to the original?

• The new size will be one-half of the original size.

• The new size will be one-fourth of the original size.

• The new size will be the same as the original size.

• The new size will be double the original size.

What are corresponding angles?

• Angles that are equal in measure

• Angles that are in the same position in different shapes

• Angles that are supplementary to each other

• Angles that are adjacent to each other

How can you use scale factors in real life?

• Scale factors are used in maps, models, and blueprints to represent larger or smaller versions of objects accurately.

• Scale factors are only used in mathematical equations and have no real-life application.

• Scale factors are used to determine the weight of objects in physics experiments.

• Scale factors are primarily used in cooking to adjust ingredient quantities.

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

• By adding the lengths of the sides of both shapes.

• By multiplying the lengths of the sides of both shapes.

• By dividing the length of a side of the larger shape by the length of the corresponding side of the smaller shape.

• By finding the average length of the sides of both shapes.

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

• 0.25

• 0.5

• 1.0

• 2.0

What happens when the scale factor is less than 1?

• It creates a reduction of the figure.

• It enlarges the figure.

• It keeps the figure the same size.

• It flips the figure upside down.

What is the relationship between scale factor and area?

• The area of a shape changes by the square of the scale factor.

• The area of a shape changes linearly with the scale factor.

• The area of a shape remains constant regardless of the scale factor.

• The area of a shape decreases by the square of the scale factor.
