Hello, my angle-loving friends! Welcome to our fun math lesson where we’ll learn how to add and subtract angles. Don’t worry, I’ll guide you through it step by step, and you’ll see how easy it is!
We measure angles using the sexagesimal system, which includes degrees, minutes, and seconds. Here’s a quick reminder: one degree equals 60 minutes, and one minute equals 60 seconds. Now, let’s dive into adding angles with some examples!
Imagine we have two angles: one is 22 degrees, 35 minutes, and 15 seconds, and the other is 63 degrees, 21 minutes, and 30 seconds. Let’s find out their sum!
First, we write the angles one below the other, just like in regular addition. Make sure degrees are under degrees, minutes under minutes, and seconds under seconds. Now, let’s add each column:
Our final result is 85 degrees, 56 minutes, and 45 seconds. Easy, right?
Let’s try another one. We have angles measuring 48 degrees, 12 minutes, and 57 seconds, and 36 degrees, 39 minutes, and 25 seconds. Let’s add them up!
Since 82 seconds is more than 60, we subtract 60 from 82, leaving us with 22 seconds, and add 1 minute to 51 minutes, making it 52 minutes. Our final result is 84 degrees, 52 minutes, and 22 seconds.
Now, let’s learn how to subtract angles. We’ll use the same system of degrees, minutes, and seconds. Here’s how it works:
We have two angles: 245 degrees, 12 minutes, and 25 seconds, and 128 degrees, 9 minutes, and 57 seconds. We place the larger angle on top and subtract the smaller one.
Our final result is 117 degrees, 2 minutes, and 28 seconds. Great job!
Now it’s your turn to practice adding and subtracting angles. With a bit of practice, you’ll become a pro in no time. Keep exploring and learning, and remember, math can be fun!

Hello, my angle-loving friends! Welcome to my new gym. How about I teach you to add angles? Don’t worry, I’ll guide you through it step by step.
We use the sexagesimal system to measure angles, which uses degrees, minutes, and seconds. You already knew that, didn’t you? Just a reminder: one degree is equal to 60 minutes, and one minute equals 60 seconds.
Today, we’ll learn how to add angles with some examples. You’ll see how easy it is! Let’s start.
We need to add the following angles: on one side, we have one measuring 22 degrees, 35 minutes, and 15 seconds, and on the other side, we have one measuring 63 degrees, 21 minutes, and 30 seconds. What would be the exact sum of both angles? Pay attention!
The first step is to put the angle measurements we want to add one below the other, just like regular addition. But be careful! The numbers have to match exactly: degrees go under degrees, minutes go under minutes, and seconds go under seconds.
Once we have placed the angles correctly, we add each column separately. We’ll start by adding the seconds: 15 seconds plus 30 seconds is 45 seconds. Now we’ll add the minutes: 35 minutes plus 21 minutes is 56 minutes. Lastly, we’ll add the degrees: 22 degrees plus 63 degrees is 85 degrees.
It’s important to remember that the answers for the seconds and minutes columns must have a value between 0 and 59. In this case, we already have the final result: 85 degrees, 56 minutes, and 45 seconds.
Now, let’s look at another example. We’re going to add the following angles: on one side, it measures 48 degrees, 12 minutes, and 57 seconds, and on the other side, it measures 36 degrees, 39 minutes, and 25 seconds. What would be the exact sum of both angles? Pay close attention!
Remember, first we must place the angle measurements we want to add one below the other. Once we have placed the angles correctly, we add each column separately. We’ll start by adding the seconds: 57 seconds plus 25 seconds is 82 seconds. Now we’ll add the minutes: 12 minutes plus 39 minutes is 51 minutes. Lastly, we’ll add the degrees: 48 degrees plus 36 degrees is 84 degrees.
Remember that the answers for the seconds and minutes columns must have a value between 0 and 59. If the minutes or seconds are more than 59, we will have to subtract 60 from them and add it to the unit to the left.
In our example, we see that we have 82 seconds, which is more than 60. We need to subtract 60 seconds from 82 seconds and move one minute to the left. This means we subtract 60 seconds from 82, leaving us with 22 seconds, and we add 1 minute to 51 minutes, giving us a total of 52 minutes.
Now, our final result is 84 degrees, 52 minutes, and 22 seconds.
Are you ready to try one on your own? Practice adding angles, and you will see how much fun it is!
Hey friends! The previous day we learned how to add angles, and today we’re going to learn how to subtract them. Are you ready?
As you know, we use the sexagesimal system to measure angles, which means they are measured in degrees, minutes, and seconds. Today, we’ll learn how to subtract angles with some examples.
The first step is to place the angle measures we want to subtract in the same format as a normal subtraction, with the smaller angle under the bigger angle. We determine which angle is larger by looking at the degrees. The angle with the largest degree will be on top. If the degrees are the same, we look at the minutes, and if they are the same as well, we look at the seconds.
The angles we will subtract are 245 degrees, 12 minutes, and 25 seconds, and 128 degrees, 9 minutes, and 57 seconds. We will place the larger angle on top.
Once we have placed the angles correctly, we subtract the seconds first, then the minutes, and finally the degrees. In the seconds column, we need to subtract 57 from 25, which is not possible. So, we will take one minute off from the minutes column and give it to the seconds. This gives us 11 minutes and 85 seconds.
Now we can subtract: 85 seconds minus 57 seconds is 28 seconds, 11 minutes minus 9 minutes is 2 minutes, and 245 minus 128 is 117 degrees.
So our final result will be 117 degrees, 2 minutes, and 28 seconds.
Good job! Wasn’t it simpler than it looked? You’ll see how quickly you can get the hang of it.

Angles – The space between two intersecting lines or surfaces at or close to the point where they meet. – In geometry class, we learned how to measure angles using a protractor.
Degrees – A unit of measurement for angles, where a full circle is 360 degrees. – The teacher asked us to draw an angle of 90 degrees on our paper.
Minutes – A unit of angular measurement equal to one-sixtieth of a degree. – When measuring angles, sometimes we use minutes to get a more precise measurement.
Seconds – A unit of angular measurement equal to one-sixtieth of a minute. – The astronomer used seconds to describe the tiny angle between the stars.
Adding – The process of combining two or more numbers to get a total. – We practiced adding the angles of a triangle to see if they always sum up to 180 degrees.
Subtracting – The process of taking one number away from another. – By subtracting the smaller angle from the larger one, we found the difference between the two angles.
Measure – To determine the size, amount, or degree of something using a standard unit. – We used a ruler to measure the length of each side of the rectangle.
System – A set of connected things or parts forming a complex whole, in particular. – The coordinate system helps us locate points on a graph accurately.
Practice – Repeated exercise in or performance of an activity to acquire or maintain proficiency in it. – We need more practice in drawing parallel lines to improve our skills.
Result – The outcome of a calculation or experiment. – The result of adding the angles in a quadrilateral is always 360 degrees.
