Right Angle

A right angle is an angle that measures exactly 90 degrees. It is one of the most important and common angles in geometry. Right angles are found in squares, rectangles, and many everyday objects like books, doors, and walls.

In diagrams, a right angle is usually marked with a small square at the corner to show it is 90°. When two lines or line segments meet to form a right angle, they are said to be perpendicular to each other.

Right angles are the foundation of many geometric constructions and are essential in fields such as architecture, engineering, and design, where precise angles are necessary. They help ensure structures are straight, balanced, and functional.

Circle

A circle is a perfectly round, two-dimensional shape in geometry where all points are equidistant from a fixed central point called the center. The distance from the center to any point on the circle is called the radius, and twice the radius is the diameter. The circumference is the total distance around the circle, and it is calculated using the formula C = 2πr, where r is the radius. The area of a circle is given by A = πr².

Circles are commonly found in nature and human-made structures—such as wheels, clocks, and coins. They have unique mathematical properties and are essential in geometry, trigonometry, engineering, and art. In addition to their practical uses, circles often symbolize unity, infinity, and harmony due to their continuous, unbroken shape.
