Similar Triangles Corresponding Parts

Front

What can be said about the angles of two similar figures?

Back

The angles of two similar figures are congruent.

Front

What is the notation used to express that triangle LMN is similar to triangle PQO?

Back

ΔLMN ∼ ΔPQO

Front

If the ratio of the side lengths of triangle XYZ to triangle ABC is 1.25, what does this imply?

Back

It implies that the sides of triangle XYZ are 1.25 times longer than the corresponding sides of triangle ABC.

Front

What criteria must be met for two triangles to be considered similar?

Back

All pairs of corresponding angles must be congruent, and the sides must be proportional.

Front

Define similarity in the context of geometric shapes.

Back

Two shapes are similar if they have the same shape but different sizes.

Front

What is the relationship between corresponding sides of similar triangles?

Back

The lengths of corresponding sides of similar triangles are in proportion.

Front

How can you determine if two triangles are similar using angle measures?

Back

If two angles of one triangle are equal to two angles of another triangle, the triangles are similar (AA criterion).

Front

What is the Side-Angle-Side (SAS) similarity criterion?

Back

If one angle of a triangle is equal to one angle of another triangle and the sides including these angles are in proportion, the triangles are similar.

Front

What does the term 'corresponding parts' refer to in similar triangles?

Back

Corresponding parts refer to angles and sides that are in the same relative position in similar figures.

Front

If triangle DEF is similar to triangle GHI, what can be said about their perimeters?

Back

The ratio of the perimeters of triangle DEF to triangle GHI is equal to the ratio of their corresponding side lengths.
