p. 6 Similar Figures Practice 2024

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. This means that their corresponding angles are equal and the ratios of their corresponding side lengths are proportional.

Front

How do you find the missing side length in similar figures?

Back

To find the missing side length in similar figures, set up a proportion using the lengths of corresponding sides from the two figures.

Front

What is the relationship between corresponding angles in similar figures?

Back

In similar figures, all pairs of corresponding angles are congruent (equal in measure).

Front

What is the definition of congruent figures?

Back

Congruent figures are figures that have the same size and shape, meaning all corresponding sides and angles are equal.

Front

If two polygons are similar, what can be said about their corresponding sides?

Back

The ratios of the lengths of corresponding sides of similar polygons are equal.

Front

What is the significance of the scale factor in similar figures?

Back

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

Front

How can you determine if two triangles are similar?

Back

Two triangles are similar if they satisfy any of the following conditions: AA (Angle-Angle) criterion, SSS (Side-Side-Side) similarity criterion, or SAS (Side-Angle-Side) similarity criterion.

Front

What is the AA criterion for triangle similarity?

Back

The AA criterion states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What does it mean for two sides to be corresponding sides?

Back

Corresponding sides are the sides of two similar figures that are in the same relative position.

Front

If triangle ABC is similar to triangle DEF, what can be said about their angles?

Back

If triangle ABC is similar to triangle DEF, then angle A = angle D, angle B = angle E, and angle C = angle F.
