Similarity

Front

What does it mean for two figures to be similar?

Back

Two figures are similar if there is a sequence of rigid transformations and dilations that moves one figure so that it fits exactly over the other.

Front

Can a sequence of transformations be applied to one figure to obtain a similar figure?

Back

True

Front

What is the scale factor in a dilation?

Back

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

Front

What transformation is used to create a mirror image of a figure?

Back

Reflection.

Front

What is the scale factor from ΔDEF to ΔABC if the corresponding sides are in the ratio of 2:1?

Back

2.

Front

What is a dilation in geometry?

Back

A dilation is a transformation that alters the size of a figure but not its shape.

Front

What does it mean for two angles to be congruent?

Back

Two angles are congruent if they have the same measure.

Front

What is the relationship between corresponding angles in similar figures?

Back

Corresponding angles in similar figures are congruent.

Front

What is the relationship between corresponding sides in similar figures?

Back

Corresponding sides in similar figures are in proportion.

Front

What transformation involves sliding a figure without changing its shape or size?

Back
