Right Angle
A right angle is an angle of exactly 90 degrees, representing a quarter turn.
History/Origin
The concept of the right angle has been used since ancient civilizations such as the Egyptians and Greeks, who formalized its measurement and significance in geometry and architecture.
Current Use
Right angles are fundamental in geometry, construction, engineering, and design, serving as a standard for perpendicularity and right-angled structures.
Circle
A circle is a geometric shape consisting of all points in a plane that are equidistant from a fixed center point.
History/Origin
The concept of the circle dates back to ancient civilizations such as the Egyptians and Greeks, who studied its properties and used it in astronomy, architecture, and mathematics. The Greek mathematician Euclid formalized many properties of the circle in his works.
Current Use
In the context of angle measurement, a circle is used as the basis for defining degrees, with 360 degrees representing a full rotation. It is fundamental in fields like geometry, engineering, and navigation for measuring angles and designing circular objects.
