What Makes Triangles Special?
Triangles are amazing shapes with three sides and three angles.
Did you know we can group triangles into different types just by looking at their side lengths? Let's explore the three main types: equilateral, isosceles, and scalene triangles!
The Three Triangle Types
1️⃣ Equilateral: All three sides are equal
2️⃣ Isosceles: Exactly two sides are equal
3️⃣ Scalene: All sides are different lengths
Equilateral
All sides equal!
Isosceles
Two sides equal!
Scalene
All sides different!

Parent Tips 🌟
- Real-world hunt: Go on a triangle hunt around your home or neighborhood and classify what you find!
- Straw triangles: Use bendy straws of different lengths to build each type of triangle.
- Pizza slices: When eating pizza, notice how most slices are isosceles triangles!
