The 90-degree angle, also known as a right angle, is one of the most prevalent angles used in architecture A right angle is an angle that is exactly equal to 90 degrees (or π/2) in measure The 90-degree angle, also known as a right angle, is one of the most prevalent angles used in architecture
. It is formed when two straight lines that are perpendicular to each other intersect at a point The term "right" indicates the conventional rectangular (or "right-angled") system of coordinates, which forms the basis for Euclidean geometry..
. We can see many real-life examples of the right angles in our daily life In geometry, a square is typically drawn at the vertex of an angle to indicate it is a right angle.
