Similarity Flashcard

Front

What does it mean for two shapes to be similar?

Back

Same shape, but different size.

Front

Which triangles are similar to triangle A?

Back

Both B and C are similar to triangle A.

Front

How do these triangles appear to be similar?

Back

SSS (Side-Side-Side similarity) means that the corresponding sides of the triangles are proportional.

Front

In similar polygons, corresponding sides are ___ and corresponding angles are ___.

Back

Corresponding sides are proportional, and corresponding angles are congruent.

Front

What is the scale factor of figure A to B if they are similar and the ratio of their corresponding sides is 1:4?

Back

The scale factor from A to B is 1:4.

Front

What is the AA criterion for triangle similarity?

Back

If two angles of one triangle are equal to two angles of another triangle, the triangles are similar.

Front

What does SSS stand for in triangle similarity?

Back

SSS stands for Side-Side-Side, indicating that all three pairs of corresponding sides are proportional.

Front

What is the SAS criterion for triangle similarity?

Back

If two sides of one triangle are proportional to two sides of another triangle and the included angles are equal, the triangles are similar.

Front

If triangle A has sides of lengths 3, 4, and 5, and triangle B has sides of lengths 6, 8, and 10, are they similar?

Back

Yes, triangle A and triangle B are similar because their corresponding sides are proportional (3:6, 4:8, 5:10).

Front

What is the relationship between the angles of similar triangles?

Back

The corresponding angles of similar triangles are congruent.
