If triangle ABC is similar to triangle DEF, and AB = 10, AC = 15, and DE = 5, what is the length of DF?

Back

DF = (DE/AB) * AC = (5/10) * 15 = 7.5.

What is the Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b): c² = a² + b².

If two triangles are similar, how do their areas compare?

Back

The areas of two similar triangles are in the ratio of the squares of their corresponding side lengths.

Front

What is a real-world application of similar triangles?

Back

Similar triangles can be used in real-world applications such as determining heights of objects using shadows or measuring distances indirectly.
