What is the definition of an adjacent side in a triangle?

Back

The adjacent side of a triangle is the side that forms one of the angles with the hypotenuse.

Front

What is the Pythagorean theorem?

Back

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. (a² + b² = c²)

Front

If the lengths of the two legs of a right triangle are 3 and 4, what is the length of the hypotenuse?

Back

5 (Using the Pythagorean theorem: 3² + 4² = 9 + 16 = 25, so hypotenuse = √25 = 5)

Front

What is the formula to calculate the length of the hypotenuse?

Back

hypotenuse = √(adjacent² + opposite²)
