Identifying a Right Angle

A right angle is an angle that forms a perfect square corner, like the corner of a book or a tile. You can check if an angle is a right angle by placing the corner of a square against it to see if it fits perfectly.

💡 If the angle is too wide or too narrow to fit the square corner, it is not a right angle.
