Similar Figures Practice

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 their corresponding sides are proportional.

Front

What does the symbol '∼' represent in geometry?

Back

The symbol '∼' stands for 'similar'.

Front

How do you find the missing side of similar figures?

Back

To find the missing side, set up a proportion using the lengths of corresponding sides of the similar figures.

Front

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

Back

If two triangles are similar, their corresponding angles are equal.

Front

What is the ratio of the sides of similar figures?

Back

The ratio of the sides of similar figures is constant and is called the scale factor.

Front

If the scale factor of two similar figures is 3:2, what does this mean?

Back

This means that for every 3 units in one figure, there are 2 corresponding units in the other figure.

Front

How can you use shadows to find the height of an object?

Back

You can use similar triangles formed by the shadow of the object and a smaller object to find the height by setting up a proportion.

Front

What is the relationship between corresponding sides of similar figures?

Back

The lengths of corresponding sides of similar figures are proportional.

Front

If a triangle has sides of lengths 6, 8, and 10, what are the lengths of the sides of a similar triangle with a scale factor of 2?

Back

The lengths of the sides of the similar triangle would be 12, 16, and 20.

Front

What does it mean for two figures to be congruent?

Back

Two figures are congruent if they have the same shape and size, meaning all corresponding sides and angles are equal.
