7.1 Similarity and Dilations HW

Front

What is the corresponding angle to angle C in similar figures?

Back

Angle F is corresponding to angle C.

Front

If two figures are similar, what can we say about their angles?

Back

The angles are congruent.

Front

Which side length corresponds with EF in similar figures?

Back

The side length LM corresponds with EF.

Front

What side corresponds to line AB in similar figures?

Back

The side DE corresponds to line AB.

Front

If two figures are similar, what can we say about their corresponding sides?

Back

The corresponding sides are proportional.

Front

Define similarity in geometry.

Back

Similarity in geometry means that two figures have the same shape but may differ in size.

Front

What is a dilation in geometry?

Back

A dilation is a transformation that alters the size of a figure but keeps its shape the same.

Front

What is the scale factor in a dilation?

Back

The scale factor is the ratio of the lengths of corresponding sides of the original figure to the dilated figure.

Front

How do you determine if two triangles are similar?

Back

Two triangles are similar if their corresponding angles are congruent and their corresponding sides are proportional.

Front

What is the relationship between the angles of similar polygons?

Back

The corresponding angles of similar polygons are equal.
