Test on Side Lengths of Similar Triangles

Front

What are similar triangles?

Back

Triangles that have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are in proportion.

Front

What is the Side Length Ratio in Similar Triangles?

Back

The ratio of the lengths of corresponding sides of similar triangles is constant.

Front

If two triangles are similar, how do you find the length of an unknown side?

Back

Use the proportion of the lengths of corresponding sides to set up a ratio and solve for the unknown side.

Front

What is the formula for finding the length of a side in similar triangles?

Back

If triangle A and triangle B are similar, then (side length of triangle A) / (side length of triangle B) = (corresponding side length of triangle A) / (corresponding side length of triangle B).

Front

If triangle ABC is similar to triangle DEF, and AB = 4, DE = 8, what is the ratio of their side lengths?

Back

The ratio is 4:8 or 1:2.

Front

What is the significance of rounding in measurements?

Back

Rounding helps simplify numbers for easier calculations and comparisons, especially in real-world applications.

Front

How do you round a number to the nearest tenth?

Back

Look at the hundredths place; if it's 5 or more, round up the tenths place by one. If it's less than 5, keep the tenths place the same.

Front

What is the relationship between the angles of similar triangles?

Back

The corresponding angles of similar triangles are equal.

Front

If the sides of triangle A are 3, 4, and 5, and triangle B is similar with the shortest side 6, what are the lengths of the other sides of triangle B?

Back

The sides of triangle B are 6, 8, and 10, maintaining the ratio of 3:4:5.

Front

What is a scale factor in similar triangles?

Back

The scale factor is the ratio of any two corresponding lengths in similar figures.
