Similar Figures + Vocabulary (Basic)

Front

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. Their corresponding angles are equal, and their corresponding sides are in proportion.

Front

What is the definition of 'corresponding' in the context of similar figures?

Back

'Corresponding' refers to matching parts of similar figures, such as angles or sides that are in the same relative position.

Front

What does 'congruent' mean?

Back

'Congruent' means that two figures or shapes are identical in shape and size; all corresponding sides and angles are equal.

Front

How can you determine the missing side of similar figures?

Back

You can determine the missing side by setting up a proportion based on the lengths of the corresponding sides of the similar figures.

Front

What is true about the angles of similar figures?

Back

Corresponding angles of similar figures are congruent.

Front

What is a proportion?

Back

A proportion is an equation that states that two ratios are equal.

Front

How do you set up a proportion to find a missing side in similar figures?

Back

To set up a proportion, you can use the ratio of the lengths of corresponding sides of the similar figures and set them equal to each other.

Front

What is the relationship between the sides of similar figures?

Back

The lengths of corresponding sides of similar figures are in the same ratio.

Front

What is the significance of scale factor in similar figures?

Back

The scale factor is the ratio of the lengths of corresponding sides of two similar figures, indicating how much one figure has been enlarged or reduced compared to the other.

Front

If two triangles are similar, what can be said about their areas?

Back

The areas of two similar triangles are in the ratio of the square of their corresponding side lengths.
