A right angle is a fundamental concept in geometry and mathematics that is formed when two lines intersect at a 90-degree angle. This angle is essential in many fields of study, including architecture, engineering, and physics. In architecture, right angles are used to create precise and stable structures, while in engineering, they are used to design machines and mechanisms that require accuracy and stability. In physics, right angles are used to calculate forces and vectors, as well as to understand the behavior of waves and particles. One of the most important properties of a right angle is its congruence. This means that all right angles are equal in measure, regardless of their size or orientation. This property is used in many mathematical proofs and theorems, including the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. Another important aspect of right angles is their classification into two subcategories: acute and obtuse. An acute right angle measures less than 90 degrees, while an obtuse right angle measures more than 90 degrees. These types of angles are used in trigonometry to calculate the values of sine, cosine, and tangent functions. Overall, right angles are a vital concept in mathematics and geometry that have numerous applications in various fields of study. Their congruence and classification into subcategories make them a fundamental building block of many mathematical proofs and theorems.

A right angle is a type of angle that measures ninety degrees. It is one of the most fundamental angles in geometry and mathematics because all of the other angles are related to it. Geometrically, a right angle is formed when two lines intersect at a ninety-degree angle. This angle is most commonly represented by a square and is used to define the cardinal directions. Mathematically, the right angle is used to define the concept of congruence and also forms the basis of trigonometry. Right angles are also featured in several theorems, including the Pythagorean theorem and the Law of Cosines. Right angle can be further classified into two subcategories: acute right angles and obtuse right angles. Acute right angles measure less than ninety degrees and obtuse right angles measure greater than ninety degrees.
