Similarity and Dilation Test

Front

What does AA Similarity mean in triangles?

Back

AA Similarity means that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What is SSS Similarity?

Back

SSS Similarity states that if the three sides of one triangle are proportional to the three sides of another triangle, then the triangles are similar.

Front

Explain SAS Similarity.

Back

SAS Similarity states that if two sides of one triangle are proportional to two sides of another triangle and the included angle is equal, then the triangles are similar.

Front

What is a similarity statement?

Back

A similarity statement expresses that two figures are similar, using the symbol '~'. For example, ΔABC~ΔDEF.

Front

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

Back

The corresponding angles of similar triangles are equal.

Front

What is the relationship between the sides of similar triangles?

Back

The corresponding sides of similar triangles are proportional.

Front

What happens to the area of a shape when it is dilated?

Back

The area of a shape is multiplied by the square of the scale factor when it is dilated.

Front

What is a scale factor in dilation?

Back

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

Front

What does it mean if the scale factor is greater than one?

Back

If the scale factor is greater than one, the dilation is an enlargement.

Front

What does it mean if the scale factor is less than one?

Back

If the scale factor is less than one, the dilation is a reduction.
