8th Grade Vocab: Pythagorean Theorem

Front

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). Formula: a² + b² = c².

What is a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.

Front

What are the sides of a right triangle called?

Back

The sides of a right triangle are called the legs (the two shorter sides) and the hypotenuse (the longest side opposite the right angle).

Front

How do you find the length of the hypotenuse?

Back

To find the length of the hypotenuse in a right triangle, use the Pythagorean Theorem: c = √(a² + b²).

Front

What is an example of using the Pythagorean Theorem?

Back

If one leg of a right triangle is 3 units and the other leg is 4 units, the hypotenuse can be found using c = √(3² + 4²) = √(9 + 16) = √25 = 5 units.

What is a rational number?

Back

A rational number is a number that can be expressed as a fraction a/b, where a and b are integers and b ≠ 0.

What is an irrational number?

Back

An irrational number is a number that cannot be expressed as a simple fraction.

Front

What is an exponent?

Back

An exponent is a number that indicates how many times to multiply a base by itself.
