Hello and welcome! Today, we’re going to learn about something called obtuse angles and see how they appear in the world around us.
Imagine you have two lines, like the hands of a clock. If one line stays still and the other moves past the 3 o’clock position, it creates an angle bigger than 90 degrees but smaller than 180 degrees. This is what we call an obtuse angle!
Obtuse angles are everywhere! Let’s look at some examples:
The blades of a windmill form angles that are bigger than 90 degrees but less than 180 degrees. These are obtuse angles!
Take a look at the letter K. One of its angles is obtuse. Can you spot it?
When you look at the roof of a house, the angle at the top is often obtuse. Next time you see a house, check it out!
Now that you know what obtuse angles are, try to find more examples around you. They might be in the playground, in your classroom, or even in your favorite toys!

Thanks for joining us today! Keep learning and have fun!
Angle Hunt: Go on a scavenger hunt around your home or classroom to find objects that have obtuse angles. Look at furniture, toys, or even books. Draw or take pictures of the objects you find and share them with your class. Can you find at least three different examples?
Build Your Own Angles: Using craft sticks or straws, create different types of angles. Try to make a right angle, an acute angle, and an obtuse angle. Compare them and see how they are different. Which one is the biggest? Which one is the smallest?
Angle Art: Create a piece of art using only obtuse angles. You can draw, paint, or use colored paper to make your design. Once you’re done, explain to someone how you know the angles in your artwork are obtuse.
Hello and welcome to Tutoring Hour! In this video, we’ll explore what obtuse angles are and how they are formed.
Let’s take two rays: we’ll keep the red ray fixed and rotate the blue ray past 90 degrees. The angle formed here is larger than 90 degrees but less than 180 degrees. This is an obtuse angle.
For example, look at the angles between the blades of a windmill; they measure somewhere between 90 degrees and 180 degrees, making them obtuse. The letter K has one obtuse angle as well.
You can also find an obtuse angle in the rooftop of a house. These are just a few examples of the many obtuse angles that surround you. Take a moment to look around for more examples!
