ClassX Video Lessons Youtube Channel TutoringHour What is an Acute Angle? Explore with Real-Life Examples
Hello and welcome! Today, we’re going to learn about something called an acute angle. It’s a fun and interesting part of geometry, which is the study of shapes and spaces.
Imagine you have two rays, which are like lines that start at one point and go off in different directions. Let’s say we have a red ray that stays still and a blue ray that we can move. When we turn the blue ray around the point where both rays meet, called the vertex, we create an angle.
An acute angle is a special kind of angle. It is bigger than 0 degrees but smaller than 90 degrees. Think of it as a small, sharp angle. If you keep turning the blue ray, the angle gets bigger, but as long as it stays less than 90 degrees, it’s still an acute angle.
Acute angles are all around us! Here are some examples you might find in everyday life:
When you look at a slice of pizza, the pointy end forms an acute angle. Yum!
Look at the letter V. The two slanting lines meet to form an acute angle at the bottom.
Hold up your hand and spread your fingers. The space between two fingers can form an acute angle.
Next time you’re out and about, see how many acute angles you can spot!

Angle Hunt: Go on an angle hunt around your home or classroom. Look for objects that have acute angles, like the corners of a book, the hands of a clock when they form a small angle, or the edges of a folded paper. Draw or take pictures of these objects and share them with your class. How many acute angles can you find?
Build Your Own Angles: Use craft sticks or straws to create different angles. Arrange two sticks to form an acute angle and use a protractor to measure it. Try making angles of different sizes and see if you can create an angle that is exactly 45 degrees. Discuss with your classmates how you know each angle is acute.
Angle Art: Create a piece of art using only acute angles. You can draw or use cut-out shapes to form a picture. For example, you might create a sun with rays that form acute angles or a mountain landscape with acute angles at the peaks. Share your artwork with the class and explain where the acute angles are in your design.
**Sanitized Transcript:**
Hello and welcome to Tutoring Hour! In this video, we’ll explore what an acute angle is and how it is formed. Let’s take these two rays; we’ll keep the red ray fixed and turn the blue one. As we turn the blue ray around this common point or vertex, you will notice an angle being formed. We’ll draw an arc to represent it like this. This angle is greater than 0 degrees and less than 90 degrees, and it is known as an acute angle. As we keep rotating, the size of the angle increases.
Take a look at this slice of pizza; it forms an acute angle. The angle formed by the two slanting lines of the letter V is acute too. Look at your hand and find an acute angle between two adjacent fingers. Just walk around, and you are likely to find many examples of acute angles.
