What is the definition of similarity in geometry?

Back

Two figures are similar if they have the same shape but not necessarily the same size. This means their corresponding angles are equal and their corresponding sides are in proportion.

Front

What does AA stand for in triangle similarity?

Back

AA stands for Angle-Angle similarity. If two angles of one triangle are equal to two angles of another triangle, the triangles are similar.

Front

What is the scale factor in dilation?

Back

The scale factor is a number that scales, or multiplies, the dimensions of a figure. A scale factor greater than 1 enlarges the figure, while a scale factor between 0 and 1 reduces it.

Front

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

Back

SAS stands for Side-Angle-Side. If two sides of one triangle are proportional to two sides of another triangle and the included angles are equal, the triangles are similar.

Front

What are corresponding sides in similar triangles?

Back

Corresponding sides are the sides of two or more similar figures that are in the same relative position.

Front

What is the relationship between corresponding angles in similar triangles?

Back

In similar triangles, corresponding angles are equal.

Front

How do you perform a dilation on a linear equation?

Back

To dilate a linear equation, multiply the coefficients of x and the constant term by the scale factor.

Front

What is the definition of corresponding angles?

Back

Corresponding angles are angles that are in the same position in different figures when the figures are similar.

Front

If triangle ABC is similar to triangle DEF, what can be said about their sides?

Back

The lengths of the corresponding sides of triangle ABC and triangle DEF are proportional.

Front

What is the formula for finding the scale factor between two similar figures?

Back

The scale factor is found by dividing the length of a side of one figure by the length of the corresponding side of the other figure.
