Unit 4 Flashcard 1

Front

What does SSS stand for in triangle similarity?

Back

SSS stands for Side-Side-Side, which indicates that if the corresponding sides of two triangles are proportional, the triangles are similar.

Front

What are the new vertices of a triangle with vertices (2,4), (4,2), (6,6) after a dilation with a scale factor of 2?

Back

The new vertices are (4,8), (8,4), (12,12).

Front

What is the relationship between similar figures in terms of shape and size?

Back

Similar figures have the same shape but different sizes.

Front

If two figures are similar, what can be said about their corresponding sides?

Back

The corresponding sides of similar figures are proportional.

Front

What is the term for the length of a side in a triangle that is being solved for?

Back

The term is 'side length'.

Front

What is the definition of dilation in geometry?

Back

Dilation is a transformation that produces a figure similar to the original by enlarging or reducing it based on a scale factor.

Front

What does AA stand for in triangle similarity?

Back

AA stands for Angle-Angle, which indicates that 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 a dilation?

Back

The scale factor is the ratio of the length of a side of the image to the length of the corresponding side of the original figure.

Front

What is the difference between congruent and similar figures?

Back

Congruent figures are identical in shape and size, while similar figures have the same shape but may differ in size.

Front

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

Back

Two triangles are similar by SAS (Side-Angle-Side) if two sides of one triangle are proportional to two sides of another triangle and the included angles are equal.
