Q2 W7 IA (Triangle Similarity)

Front

What is the AA similarity criterion for triangles?

Back

The AA (Angle-Angle) similarity criterion states that if two angles of one triangle are equal to two angles of another triangle, then the two triangles are similar.

Front

What is the SAS similarity criterion for triangles?

Back

The SAS (Side-Angle-Side) similarity criterion 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 is the SSS similarity criterion for triangles?

Back

The SSS (Side-Side-Side) similarity criterion states that if the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

If two triangles are similar, what can be said about their corresponding sides?

Back

The corresponding sides of similar triangles are proportional.

Front

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

Back

The corresponding angles of similar triangles are equal.

Front

What is the definition of similar triangles?

Back

Similar triangles are triangles that have the same shape but may differ in size; their corresponding angles are equal and their corresponding sides are in proportion.

Front

How can you prove that two triangles are similar using the AA criterion?

Back

To prove triangles are similar using the AA criterion, show that two angles of one triangle are equal to two angles of another triangle.

Front

How can you prove that two triangles are similar using the SAS criterion?

Back

To prove triangles are similar using the SAS criterion, show that two sides of one triangle are proportional to two sides of another triangle and that the included angles are equal.

Front

How can you prove that two triangles are similar using the SSS criterion?

Back

To prove triangles are similar using the SSS criterion, show that the lengths of the corresponding sides of the triangles are in proportion.

Front

What is a scale factor in the context of similar triangles?

Back

The scale factor is the ratio of the lengths of corresponding sides of two similar triangles.
