FLASHCARD QUESTION

Front

What are similar triangles?

Back

Triangles that have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are proportional.

2.

FLASHCARD QUESTION

Front

What does it mean for sides to be proportional in similar triangles?

Back

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

3.

FLASHCARD QUESTION

Front

If triangle A is similar to triangle B, and the length of a side in triangle A is 4 cm, what is the length of the corresponding side in triangle B if the ratio of similarity is 2:1?

Back

2 cm.

FLASHCARD QUESTION

Front

What is the Angle-Angle (AA) similarity criterion for triangles?

Back

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

5.

FLASHCARD QUESTION

Front

How can you find the height of an object using similar triangles?

Back

By creating a proportion using the lengths of corresponding sides from a smaller triangle (formed by a shadow or a measurement) and the larger triangle (the object itself).

FLASHCARD QUESTION

Front

If two triangles have sides of lengths 3 cm, 4 cm, and 5 cm, and another triangle has sides of lengths 6 cm, 8 cm, and 10 cm, are they similar?

Back

Yes, because the sides are in proportion (1:2).

7.

FLASHCARD QUESTION

Front

What is the Side-Side-Side (SSS) similarity criterion?

Back

If the lengths of the corresponding sides of two triangles are proportional, then the triangles are similar.
