rechtswinklig

"Rechtswinklig" is a German term that translates to "right-angled" in English. It refers to a shape or angle that is exactly 90 degrees. In geometry, a right angle is formed by two lines that intersect at a 90-degree angle, creating a square corner. This term is commonly used in mathematics, architecture, and engineering to describe perpendicular lines or surfaces.

The concept of a right angle is fundamental in various fields. In mathematics, right angles are crucial for defining shapes like squares and rectangles, and for calculating distances and areas. In architecture, right angles are essential for constructing stable and symmetrical structures. In engineering, right angles are used in the design of machinery and tools to ensure precision and functionality.

The term "rechtswinklig" can also be used to describe a triangle that has one right angle, known as a right-angled triangle. This type of triangle has unique properties, such as the Pythagorean theorem, which states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In everyday language, "rechtswinklig" can be used to describe something that is perfectly perpendicular or at a 90-degree angle to something else. For example, a wall that is "rechtswinklig" to the floor is perpendicular to it.
