Back

The intersection of two planes is a line.

Front

What does it mean for two objects to be congruent?

Back

They have the same shape and size.

Front

What does the SSS triangle congruence theorem state?

Back

If three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

What happens when the scale factor is less than one?

Back

The new figure will be a reduction.

Front

What is a reflection in geometry?

Back

A transformation that flips a figure over a line.

Front

What is the definition of a transformation?

Back

A change in the position, size, or shape of a figure.

Front

What does the term 'scale factor' refer to?

Back

The ratio of the lengths of two corresponding sides of two similar figures.

Front

What is the difference between similar and congruent figures?

Back

Similar figures have the same shape but not necessarily the same size; congruent figures have the same shape and size.

Front

What is the ASA triangle congruence theorem?

Back

If two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are congruent.

Front

What is a translation in geometry?

Back

A transformation that moves every point of a figure the same distance in the same direction.
