Similar Triangles Flashcard

Front

What is the SSS similarity postulate?

Back

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

Front

What is the SAS similarity postulate?

Back

If two pairs of sides of two triangles are proportional and the included angles are congruent, then the triangles are similar.

Front

What is the AA similarity postulate?

Back

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

Front

If the corresponding angles of two triangles are equal, are the triangles similar?

Back

Yes.

Front

What does it mean for triangles to be similar?

Back

Triangles are similar if they have the same shape but not necessarily the same size.

Front

How do you determine if two triangles are similar using the SSS postulate?

Back

Check if the ratios of the lengths of corresponding sides are equal.

Front

How do you determine if two triangles are similar using the SAS postulate?

Back

Check if two pairs of sides are proportional and the included angles are equal.

Front

What is the relationship between the areas of similar triangles?

Back

The ratio of the areas of two similar triangles is equal to the square of the ratio of their corresponding sides.

Front

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

Back

The corresponding angles are equal.

Front

If the lengths of RV is 5 and QR is 8, what is the ratio of RV to QR?

Back

The ratio is 5:8.
