G-6.1 FLASHCARD Similarity

Front

What does it mean for two figures to be similar?

Back

Two figures are similar if they have the same shape but may differ in size. Their corresponding side lengths are proportional.

Front

What is the definition of proportionality in geometry?

Back

Proportionality in geometry refers to the relationship between two quantities where their ratio remains constant.

Front

How can you determine if two quadrilaterals are similar?

Back

To determine if two quadrilaterals are similar, check if their corresponding angles are equal and their corresponding side lengths are proportional.

Front

What is the significance of corresponding sides in similar figures?

Back

Corresponding sides in similar figures are the sides that are in the same relative position. Their lengths are proportional in similar figures.

Front

If two figures are the same shape but not the same size, are they similar?

Back

Yes, if two figures are the same shape, they are similar, regardless of their size, as long as their corresponding sides are proportional.

Front

What is an example of similar figures?

Back

An example of similar figures is two triangles where one triangle is a scaled version of the other, maintaining the same angles.

Front

What does it mean if two figures are not similar?

Back

If two figures are not similar, it means they do not have the same shape or their corresponding side lengths are not proportional.

Front

What is the relationship between angles in similar figures?

Back

In similar figures, corresponding angles are equal.

Front

Can two figures be similar if they have different orientations?

Back

Yes, two figures can be similar even if they are rotated or flipped, as long as their shapes and proportions are maintained.

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.
