Triangle Similarity(intro)

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 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

What does SSS stand for in triangle similarity?

Back

SSS stands for Side-Side-Side similarity, which states that if the three sides of one triangle are in proportion to the three sides of another triangle, the triangles are similar.

Front

What is the criteria for two triangles to be similar?

Back

Two triangles are similar if they meet any of the following criteria: AA, SAS, or SSS.

Front

If two triangles have one angle of 60 degrees and another angle of 30 degrees, what can be said about their similarity?

Back

The triangles are similar by AA similarity because they have two angles that are equal.

Front

How can you determine if two triangles are not similar?

Back

Two triangles are not similar if they do not meet any of the similarity criteria: AA, SAS, or SSS.

Front

If DE is parallel to KJ, how can you find the missing side using proportions?

Back

You can set up a proportion based on the lengths of the sides of the triangles formed by the parallel lines and solve for the missing side.

Front

What is the significance of parallel lines in triangle similarity?

Back

Parallel lines create similar triangles by forming corresponding angles that are equal.

Front

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

Back

The corresponding sides of triangle ABC and triangle DEF are in proportion.

Front

What is the relationship between the angles of similar triangles?

Back

The corresponding angles of similar triangles are equal.
