Right angles are justified primarily by their fundamental properties in geometry, where they represent a 90-degree angle, establishing a standard for perpendicularity. This characteristic is crucial in various applications, including construction and design, ensuring structures are stable and properly aligned. Additionally, right angles serve as the basis for defining trigonometric functions and contribute to the Pythagorean theorem, which connects the sides of right triangles. Thus, their significance extends beyond mere definition to practical applications in mathematics and real-world scenarios.

How many right angles do a kite have?

A kite has 4 right angles (all angles of the kite are right angles), since the kite is parallel. If the kite was cyclic, then 2 right angles. And if normal kite, then 0 right angles.


Can an obtuse triangle have a right angle as one of its angles give reason?

No The reason is that an obtuse angle is over 90o so with a second angle of 90o you already have angles totalling more than 180o which is impossible in a triangle.
