Front

If two triangles are similar, how does their area relate?

Back

The area of similar triangles is proportional to the square of the ratio of their corresponding sides.

Front

What is the Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

Front

If the lengths of the legs of a right triangle are 6 and 8, what is the length of the hypotenuse?

Back

Using the Pythagorean theorem: Hypotenuse = √(6² + 8²) = √(36 + 64) = √100 = 10.
