What is the Triangle Similarity Theorem?

Back

The Triangle Similarity Theorem states that if two triangles have corresponding angles that are equal, then the triangles are similar, meaning their corresponding sides are in proportion.

Front

What does AA Similarity mean?

Back

AA Similarity (Angle-Angle Similarity) means that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What does SAS Similarity mean?

Back

SAS Similarity (Side-Angle-Side Similarity) states that if two sides of one triangle are in proportion to two sides of another triangle and the included angles are equal, then the triangles are similar.

Front

What does SSS Similarity mean?

Back

SSS Similarity (Side-Side-Side Similarity) states that if the three sides of one triangle are in proportion to the three sides of another triangle, then the triangles are similar.

What is the Triangle Angle Bisector Theorem?

Back

The Triangle Angle Bisector Theorem states that the angle bisector of an angle in a triangle divides the opposite side into segments that are proportional to the other two sides.

How do you set up proportions using the Triangle Angle Bisector Theorem?

Back

Front

Which theorem states that if two triangles have one angle equal and the sides including those angles are in proportion, then the triangles are similar?

Back

This is known as the SAS Similarity Theorem.

Front

What is the significance of the AA Similarity Theorem in solving problems?

Back

The AA Similarity Theorem allows us to conclude that two triangles are similar if we can show that two pairs of corresponding angles are equal, simplifying many geometric problems.

What is a common misconception about triangle similarity theorems?

Back

A common misconception is that ASA (Angle-Side-Angle) is a similarity theorem; however, it is not recognized as a separate theorem for triangle similarity.

Front

How can you determine if two triangles are not similar?

Back

If the corresponding angles are not equal or the sides are not in proportion, then the triangles are not similar.
