Also known as square angle

90° angle (π/2 radians): an angle that bisects the angle formed by two halves of a straight line

AI overview

A right angle is a 90-degree angle formed when two lines meet at a perfect quarter-turn, dividing a straight line into two equal parts. Right angles matter because they're fundamental to construction, design, and mathematics—they appear everywhere from building corners to coordinate systems and help us measure and organize space precisely.
