GEO. - Q2: WEEK #7 FLASHCARD

Front

What are scale drawings?

Back

Scale drawings are representations of objects that maintain the same proportions as the original, but are either larger or smaller. They are used to accurately depict the dimensions of an object in a different size.

Front

What is a scale factor?

Back

A scale factor is a number that scales, or multiplies, some quantity. In the context of scale drawings, it indicates how much larger or smaller the drawing is compared to the original.

Front

What does it mean for two figures to be similar?

Back

Two figures are similar if they have the same shape but may differ in size. Their corresponding side lengths are proportional.

Front

How do you determine if two figures are similar?

Back

To determine if two figures are similar, check if their corresponding angles are equal and their corresponding side lengths are proportional.

Front

What is a ratio?

Back

A ratio is a relationship between two numbers indicating how many times the first number contains the second. It can be expressed in various forms, such as a fraction, with a colon, or in words.

Front

How do you simplify a ratio?

Back

To simplify a ratio, divide both terms by their greatest common divisor (GCD) until no further simplification is possible.

Front

What is the ratio of 3 coaches to 10 players?

Back

The ratio of coaches to players is 3:10.

Front

What is an enlargement in geometry?

Back

An enlargement is a transformation that increases the size of a figure by a scale factor greater than 1, while maintaining its shape.

Front

What is a reduction in geometry?

Back

A reduction is a transformation that decreases the size of a figure by a scale factor less than 1, while maintaining its shape.

Front

If the scale factor is 5, what type of transformation is it?

Back

If the scale factor is 5, the transformation is an enlargement.
