What kind of angle is created by the intersection of two perpendicular lines, rays, or line segments?

When two lines, rays, or line segments intersect at a right angle, they create what is known as a right angle. A right angle is defined as an angle that measures exactly $90^\circ$ or $\frac{\pi}{2}$ radians.

In geometry, perpendicular lines are those that intersect at right angles. This principle is fundamental in both theoretical and practical applications across various fields, including architecture, engineering, and mathematics. The right angle is commonly represented by a small square placed at the vertex of the angle to indicate that it is indeed $90^\circ$.

In summary, the kind of angle formed by the intersection of two perpendicular lines, rays, or line segments is a right angle, measuring $90^\circ$.
