Similar Triangles flashcard-RJ

Front

What does AA stand for in triangle similarity?

Back

AA stands for Angle-Angle similarity, which states that 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 similarity, which states that if the corresponding sides of two triangles are in proportion, the triangles are similar.

Front

What does SAS stand for in triangle similarity?

Back

SAS stands for Side-Angle-Side similarity, which states that if two sides of one triangle are in proportion to two sides of another triangle and the included angles are equal, the triangles are similar.

Front

How can you determine if two triangles are similar?

Back

You can determine if two triangles are similar by using the AA, SSS, or SAS criteria.

Front

If two triangles have one angle of 60 degrees and another angle of 30 degrees, are they similar?

Back

Yes, they are similar by AA similarity.

Front

What is the relationship between the sides of similar triangles?

Back

The corresponding sides of similar triangles are in proportion.

Front

If triangle ABC is similar to triangle DEF, and AB = 4 cm, DE = 8 cm, what is the ratio of their sides?

Back

The ratio of their sides is 1:2.

Front

In triangle similarity, what does it mean if two triangles are 'not similar'?

Back

It means that the triangles do not meet any of the criteria for similarity (AA, SSS, SAS) and their corresponding angles and sides are not proportional.

Front

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

Back

Yes, they are similar by SSS similarity.

Front

What is a proportion in the context of similar triangles?

Back

A proportion is an equation that states that two ratios are equal, often used to compare the lengths of corresponding sides of similar triangles.
