Similar Figures

Front

What are similar figures?

Back

Similar figures are shapes that have the same shape but may differ in size. Their corresponding angles are equal, and the ratios of their corresponding sides are proportional.

Front

How can you determine if two figures are similar?

Back

To determine if two figures are similar, check if their corresponding angles are equal and if the ratios of their corresponding sides are equal.

Front

What does it mean for sides to be proportional in similar figures?

Back

Sides are proportional in similar figures when the ratio of the lengths of corresponding sides is the same across all pairs of sides.

Front

Are two similar figures also congruent? Why or why not?

Back

No, two similar figures are not necessarily congruent. Congruent figures are identical in shape and size, while similar figures have the same shape but can differ in size.

Front

What is the relationship between the angles of similar figures?

Back

The corresponding angles of similar figures are always equal.

Front

If two triangles have sides in the ratio of 2:3, are they similar?

Back

No, they are not similar because the sides must be in equal ratios for all corresponding sides.

Front

Can two figures be similar if they have different shapes?

Back

No, two figures cannot be similar if they have different shapes. They must have the same shape.

Front

What is an example of similar figures in real life?

Back

An example of similar figures in real life is a map and the actual geographical area it represents; both have the same shape but different sizes.

Front

If two rectangles have the same length-to-width ratio, what can be said about them?

Back

If two rectangles have the same length-to-width ratio, they are similar.

Front

What is the significance of the scale factor in similar figures?

Back

The scale factor is the ratio of the lengths of corresponding sides of similar figures, indicating how much one figure is enlarged or reduced compared to the other.
