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). It can be expressed as: c² = a² + b².

If one leg of a right triangle is 3 cm and the other leg is 4 cm, what is the length of the hypotenuse?

Back

Using the Pythagorean Theorem: c² = 3² + 4²; c² = 9 + 16; c² = 25; c = 5 cm.

What is the length of the diagonal of a rectangle with a width of 50 yards and a length of 100 yards?

Back

Using the Pythagorean Theorem: d² = 50² + 100²; d² = 2500 + 10000; d² = 12500; d = 111.8 yards.

What is the length of the missing side if one leg is 8 cm and the hypotenuse is 10 cm?

Back

Using the Pythagorean Theorem: 10² = 8² + b²; 100 = 64 + b²; b² = 36; b = 6 cm.

What is the area of a right triangle with legs of 6 cm and 8 cm?

Back

Area = (1/2) * base * height = (1/2) * 6 cm * 8 cm = 24 cm².
