Unit 6 Review

Front

What does it mean for two triangles to be similar?

Back

Two triangles are similar if their corresponding angles are equal and their corresponding sides are in proportion.

Front

How do you determine the measurement of a variable in similar triangles?

Back

You can use the properties of similar triangles, where the ratios of corresponding sides are equal, to set up a proportion and solve for the variable.

Front

If triangle A has sides of 2 ft and triangle B has sides of 4 ft, are they similar?

Back

Yes, because the corresponding sides are in proportion (2:4 or 1:2).

Front

What is the relationship between the angles of similar triangles?

Back

The corresponding angles of similar triangles are equal.

Front

If 1 kg equals 2.2 lbs, how do you convert lbs to kg?

Back

To convert lbs to kg, divide the number of pounds by 2.2.

Front

What is the formula to convert kg to lbs?

Back

To convert kg to lbs, multiply the number of kilograms by 2.2.

Front

If two triangles have sides of lengths 3 ft and 6 ft, are they similar?

Back

Yes, because the ratio of their sides (3:6 or 1:2) indicates similarity.

Front

What is the significance of the ratio of corresponding sides in similar triangles?

Back

The ratio of corresponding sides in similar triangles is constant and equal to the ratio of any two corresponding sides.

Front

If triangle A has angles of 30°, 60°, and 90°, what are the angles of a similar triangle?

Back

The angles of a similar triangle will also be 30°, 60°, and 90°.

Front

How can you verify if two triangles are similar using side lengths?

Back

You can verify similarity by checking if the ratios of the lengths of corresponding sides are equal.
