Front

What does AA stand for in triangle similarity?

Back

AA stands for Angle-Angle, a criterion for triangle similarity where two angles of one triangle are equal to two angles of another triangle.

Front

What is the scale factor in similar triangles?

Back

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

Front

How can you determine if two triangles are similar using SAS?

Back

SAS stands for Side-Angle-Side, a criterion for triangle similarity where two sides of one triangle are proportional to two sides of another triangle, and the included angle is equal.

Front

What does SSS mean in the context of triangle similarity?

Back

SSS stands for Side-Side-Side, a criterion for triangle similarity where all three sides of one triangle are proportional to the three sides of another triangle.

Front

If the scale factor from triangle DEF to triangle ABC is 2, what does this mean?

Back

It means that each side of triangle ABC is twice the length of the corresponding side of triangle DEF.

Front

What is the transformation called when a shape is flipped over a line?

Back

This transformation is called Reflection.

Front

What is the transformation called when a shape is turned around a point?

Back

This transformation is called Rotation.

Front

What is the transformation called when a shape is slid from one position to another?

Back

This transformation is called Translation.

Front

If the scale factor from triangle F to triangle E is 3, what does this indicate?

Back

It indicates that each side of triangle E is three times the length of the corresponding side of triangle F.

Front

What is the relationship between similar triangles and their angles?

Back

In similar triangles, corresponding angles are equal.
