Is it a scaled copy?

Front

What is a scaled copy in geometry?

Back

A scaled copy is a figure that is similar to another figure but is either larger or smaller by a certain scale factor. The corresponding angles are equal, and the lengths of corresponding sides are proportional.

How do you determine if two figures are scaled copies of each other?

Back

Two figures are scaled copies if their corresponding angles are equal and the lengths of corresponding sides are in the same ratio (scale factor).

What is the significance of the order of letters in naming sides of geometric figures?

Back

The order of letters indicates the corresponding sides of the figures. For example, if triangle ABC is similar to triangle DEF, then side AB corresponds to side DE, side BC corresponds to side EF, and side CA corresponds to side FD.

If a side length in the original figure is 4 units and the scale factor is 2, what is the length of the corresponding side in the scaled copy?

Back

The length of the corresponding side in the scaled copy would be 8 units (4 units x 2).

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 corresponding sides of two similar figures.

If triangle ABC is a scaled copy of triangle DEF with a scale factor of 3, and side AB is 5 units, what is the length of side DE?

Back

The length of side DE would be 15 units (5 units x 3).

How can you find the missing side length in a scaled copy if you know the scale factor?

Back

You can find the missing side length by multiplying the known side length by the scale factor if the original figure's side length is known, or by dividing the scaled copy's side length by the scale factor if the scaled copy's side length is known.

What does it mean for two figures to be similar?

Back

Two figures are similar if they have the same shape but not necessarily the same size, meaning their corresponding angles are equal and their corresponding sides are proportional.

If side BC in the original figure corresponds to side NO in the scaled copy, what can you infer about their lengths?

Back

The lengths of side BC and side NO are proportional based on the scale factor of the scaled copy.
