3:60 is a mathematical angle, which can be understood as the angle between 3 o'clock position and 60 minutes position. In mathematics, we usually use degrees to measure angles. A complete circle has 360 degrees. Therefore, 3:60 can be converted into a standard degree representation, which is 90 degrees.

From a geometric point of view, an angle is composed of two rays or line segments, one of which is called the starting edge and the other is called the trailing edge. The start edge is fixed, and the end edge can rotate around the start edge to form different angles. On the clock, the hour scale indicates the position of the starting edge and the minute scale indicates the position of the ending edge. When the end edge points to 60 minutes, the angle it forms with the start edge is the angle represented by 3:60.

This included angle is actually a right angle, which is 90 degrees. Right angle is one of the most basic and common angles, which has important applications in geometry and physics. For example, in architectural design, when it is necessary to maintain the vertical relationship between the wall and the ground, right angles are used.

3:60 not only represents a right angle, but also can be understood as an obtuse angle. An obtuse angle is an angle greater than 90 degrees but less than 180 degrees. When the hour scale and minute scale on a clock form an included angle of more than 90 degrees and less than 180 degrees, we can call it an obtuse angle.

Mathematically, 3:60 is a right angle of 90 degrees or an obtuse angle greater than 90 degrees and less than 180 degrees. This concept has important applications in geometry and physics, helping us to understand and describe the angles and relationships between different shapes.
