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

A right angle is a type of angle that measures exactly 90 degrees. It is formed when two lines or line segments intersect each other and create a square corner, forming a “L” or “90-degree” shape. The sides of a right angle are perpendicular to each other, meaning they are in a position of 90-degree separation.

In geometry, right angles are commonly represented by a small square at the vertex where the lines intersect or by the symbol ” ∟ “. The symbol ” ∟ ” is placed at the vertex of the angle to indicate that it is a right angle.

Right angles can be found in many objects and shapes in our daily lives. For example, the corners of a square, rectangle, or any other rectangular object form right angles. Also, the intersection between the sides of a cube or a regular hexagon creates right angles as well.

The significance of right angles in mathematics and engineering is immense. They possess several unique properties that make them useful in various applications, such as construction, architecture, and geometry. One important property of right angles is that the sum of all angles in any triangle is always 180 degrees. This means that if one angle in a triangle is a right angle, the other two angles must add up to 90 degrees.

Overall, right angles play a fundamental role in understanding geometric shapes, measuring angles, and solving problems related to angles and triangles.
