Hello my wonderful Grade 5 superstar! 👋
I'm Kashef and today we're learning about Reflex Angles! A reflex angle is bigger than a straight angle — it measures more than 180° but less than 360°. It's the "outside" or bigger angle you see when two lines meet. Ready to explore the biggest angles? Let’s go! 🚀
🧠 What is a Reflex Angle?
A reflex angle measures more than 180° but less than 360°.
It is the larger angle when two lines cross.
The big curved part is the reflex angle (more than 180°)
🔄 All Types of Angles
- Acute → Less than 90°
- Right → Exactly 90°
- Obtuse → More than 90° but less than 180°
- Straight → Exactly 180°
- Reflex → More than 180° but less than 360°
