The Pythagorean theorem, a cornerstone of mathematics for millennia, provides a method for determining unknown sides in right ...

The cosine of this angle is the length of the horizontal side divided by the hypotenuse. The Pythagorean theorem is therefore equivalent to the equation sin 2 x + cos 2 x = 1.

The transition from basic arithmetic to geometric reasoning often proves daunting, leaving many students struggling to connect abstract formulas with practical applications. However, understanding key ...

The hypotenuse of a right triangle is the triangle's longest side; the side opposite the right angle. The length of the hypotenuse of a right triangle can be found using the Pythagorean theorem ...

In the world of taxicab geometry, even the Pythagorean theorem takes a back seat.

July 24th (7/24) is considered "Pythagorean Theorem Day" because the date itself represents a Pythagorean triple: when you square 7 (the first number) and 24 (the second number), the sum equals the ...

Pythagoras’ theorem can then be used on either of the two right-angled triangles. The 25 cm length becomes the hypotenuse so should be labelled 𝒄.

The 2,000 year-old theorem states that the sum of the squares on the legs of a right triangle is equivalent to the square on the hypotenuse, or the longest side of a right triangle.
