Hello my wonderful Grade 5 superstar! 👋
I'm Kashef and today we're learning about Right Angles! A right angle is exactly 90 degrees — the same as the corner of a square or a book. It's the "just right" angle! Ready to find perfect corners everywhere? Let’s go! 🚀
🧠 What is a Right Angle?
A right angle measures exactly 90°.
It looks like the letter "L" or the corner of a square.
This is a right angle → It has a small square symbol in the corner.
