Sextant

A sextant is a navigational instrument used to measure the angle between two visible objects, most commonly between the horizon and a celestial body like the sun, moon, or stars. It helps sailors determine their latitude and longitude while at sea, making it essential for marine navigation before the age of GPS.

The sextant consists of a frame with a graduated arc marked in degrees, a movable arm called an index arm, and mirrors to sight the objects. By measuring the angle accurately, navigators can calculate their position on the Earth’s surface using mathematical tables.

Invented in the 18th century, the sextant revolutionized navigation by allowing more precise and reliable open-sea travel. Even today, it remains a valuable backup tool for sailors and navigators.

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.
