Hello my wonderful Grade 5 superstar! 👋
I'm Kashef and today we're exploring Triangles! Triangles are everywhere — in bridges, roofs, and even slices of pizza! They are super strong shapes with 3 sides and 3 angles. Ready to become a Triangle Expert? Let’s go! 🚀
🔺 Types of Triangles
By Sides:
- Equilateral — All sides equal, all angles 60°
- Isosceles — Two sides equal
- Scalene — All sides different
By Angles:
- Right Triangle — Has a 90° angle
- Acute Triangle — All angles less than 90°
- Obtuse Triangle — One angle more than 90°
📐 Important Triangle Facts
🔹 All triangles have 3 sides and 3 angles
🔹 The sum of the angles is always 180°
🔹 The bigger the angle, the longer the opposite side
