RIGHTANGLED Meaning and
Definition
-
The term "rightangled" refers to an object, shape, or structure that possesses a right angle. A right angle is defined as an angle that measures exactly 90 degrees, forming a perfect L-shape. It is characterized by two perpendicular lines, intersecting at a point, in which each line is inclined at an angle of 90 degrees relative to the other. The sides formed by these lines are typically of equal length, resulting in an isosceles right triangle.
In mathematics, rightangled shapes are of great importance in geometry, trigonometry, and other related fields. Within a right triangle, the side opposite the right angle is known as the hypotenuse, while the other two sides are called the legs. Various geometric properties of rightangled shapes contribute to the development of mathematical concepts, such as the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the legs.
Outside of mathematics, the term "rightangled" is also used more broadly to describe any object or structure that has a right angle. For instance, in carpentry and architecture, rightangled corners are highly sought after due to their stability and symmetry. Furthermore, rightangled shapes often form the basis for constructing rectangular structures, such as buildings, windows, doors, and furniture, which are commonly found in our everyday surroundings.

Etymology of RIGHTANGLED
The word "rightangled" combines two separate terms - "right" and "angled".
The word "right" comes from the Old English word "riht", which means "straight" or "correct". It can be traced back to the Proto-Germanic word "rehtaz" and the Proto-Indo-European root "*reg-" meaning "to move in a straight line".
The term "angled" comes from the Middle English word "angelen", which derives from the Old English word "angul", meaning "corner" or "angle". The Old English word itself has origins in the Latin word "angulus", meaning "corner" or "bend".
So, when combined, "rightangled" literally means "having a corner or angle that is straight or correct". In mathematics, it specifically refers to an angle that measures 90 degrees, forming a right angle.
