A right angle is a type of angle in geometry that measures exactly 90 degrees

A right angle is a type of angle in geometry that measures exactly 90 degrees. It is formed when two line segments or rays intersect each other, creating four angles around the point of intersection. A right angle is often depicted as a small square or a box-like symbol (∟) placed at the vertex where the lines meet.

In a right angle, the two arms or sides of the angle are perpendicular to each other, meaning they form a 90-degree angle. The perpendicular lines are said to be “at right angles” to each other because they create equal angles on either side. This characteristic of a right angle makes it an essential concept in many mathematical and practical applications.

Right angles have numerous applications in real-life situations and are prevalent in geometry and trigonometry. They are commonly found in shapes such as squares and rectangles, where the corners are right angles. Right angles are crucial in construction, architecture, and engineering as they provide stability and support. They can also be seen in various tools and objects, such as the corners of books, computer screens, or doors.

Moreover, right angles are the building blocks of trigonometric functions like sine, cosine, and tangent. These functions play a significant role in solving problems involving angles and distances in trigonometry and physics. For example, in trigonometry, a right triangle has one angle measuring 90 degrees, resulting in the identification of ratios between its sides. These ratios form the basis for many calculations related to angles, distances, and heights.

In summary, a right angle is a 90-degree angle formed when two lines intersect, with the arms or sides of the angle being perpendicular to each other. It is a fundamental concept in geometry and is widely used in various fields and applications.
