In today’s post, we’re going to take a look at the relationship between clocks and angles.

More specifically, we’ll see the kinds of angles that can be formed by the hands of a clock and how to calculate them.

On a clock, we can see different kinds of angles based on its amplitude; void, acute, straight, obtuse, flat angles—even a full angle.

Let’s check out some examples.

In this first example, we can see that the angle formed by the hands is an **acute angle** because it’s** less than 90° and more than 0°.**

On the next clock, where the hands point to 6 o’clock sharp, the hands form a **180° ****flat angle.**

In our last example, we have a clock where the hands form a **full angle****,** that is, an angle that’s** 360°.**

**Now, we’re going to see how we can calculate an angle that’s formed by the two hands of a clock at whatever time. We could use a protractor but, if we don’t have one handy, how can we calculate angles?**

We can start by looking at the minute hand, the long hand that indicates the minutes.

The minute hand covers 360° when it completes its cycle, in other words, an hour. There are a total of 60 minutes in an hour, so each minute is 6°.

Below, we’re going to see how the hour hand goes by, which is the short hand that indicates the hours.

If we divide a complete round (360°) by the total number of hours (12 hours), we get 30°. That is to say, the hour hand moves 30° per hour.

If in one hour, which is 60 minutes, the hour hand moves 30°, it’ll move 0.5° in one minute, as we can see in the next picture.

Now, let’s get busy and calculate the angle formed by the hands that point to 5 o’clock sharp.

What angle will the clock hands make after 10 minutes?
