What does it mean for two figures to be similar?

Back

Two figures are similar if they have the same shape but not necessarily the same size. Their corresponding angles are equal, and the lengths of their corresponding sides are proportional.

Front

How do you set up a proportion to find a missing side in similar figures?

Back

To set up a proportion, you can use the ratio of the lengths of corresponding sides. If two figures are similar, then the ratio of one pair of corresponding sides is equal to the ratio of another pair of corresponding sides.

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

Front

If the scale factor of two similar triangles is 2, what does this imply about their corresponding sides?

Back

If the scale factor is 2, it means that each side of the larger triangle is twice the length of the corresponding side of the smaller triangle.

Front

How do you find the missing side length using proportions?

Back

To find the missing side length, set up a proportion using the known side lengths of the similar figures and solve for the unknown side.

Front

What is the relationship between the angles of similar figures?

Back

The corresponding angles of similar figures are equal.

Front

If triangle ABC is similar to triangle DEF, and the length of side AB is 4 and side DE is 8, what is the scale factor?

Front

How do you calculate the missing side if you know one side and the scale factor?

Back

Multiply the known side length by the scale factor to find the missing side length.
