WebWhen two rays intersect and form a 90˚ angle at the intersection, they are said to form a right angle. It is the most commonly seen angle in our day-to-day life. We can see it in many places like the corners of a window, the edges of a cupboard, the screen of a mobile phone, and so on. WebRays do not have finite length as by definition they keep going straight on their indicated direction on to infinity. It is only a line segment that does so.
