Summary

🎉 Exciting Summary of Triangles 🎉 To conclude the lesson on a high note, let's do a quick recap in the form of Top 5 Facts about triangles! 🏆

1. Equilateral Triangle: All sides and angles are equal! A true symbol of symmetry. 🎨
2. Isosceles Triangle: Features two equal sides and one different, along with two equal angles. It’s the triangle of inseparable pairs. 👯
3. Scalene Triangle: All sides and angles are unique; it’s the 'everyone for themselves' triangle. 🔀
4. Angles: Can be acute (less than 90°), right (exactly 90°), or obtuse (greater than 90°). 🎯
5. Role in Architecture: Triangles are key to stable architectural designs due to their strength and load distribution. 🏛️
