What does a 90 degree angle look like in a diagram?

Answer 1

A 90-degree angle in a diagram is typically represented by two lines that intersect at a point, forming a corner that resembles the letter "L." One line is vertical, while the other is horizontal, creating a right angle. Often, a small square symbol is placed at the vertex to indicate that it is a right angle. This visual representation helps to easily identify the angle's measurement as 90 degrees.
