90 Degree Angle Formula

Let us recollect a few things about a 90-degree angle before understanding the 90-degree angle calculation. When the angle formed by two rays equals 90 degrees, the angle is termed a right angle. In a right-angled triangle, Pythagoras' theorem is used. It asserts that the sum of the squares of the lengths of a right triangle's adjacent and opposite sides equals the square of the hypotenuse side's length. The correct angle can also be determined using this 90-degree angle calculation.

The Pythagoras theorem of a right triangle, as the triangle with a 90-degree angle is a right triangle, is the source of the 90-degree angle formula

i.e.,

Hypotenuse²=(Adjacent Side)² + (Opposite Side)²

a² + b² = c²
