Understanding Triangles
Triangles are one of the most fundamental shapes in geometry. Here's why they are special:
- They have three sides and three angles.
- The sum of the internal angles is always 180 degrees.
- Triangles can be classified into various types: equilateral, isosceles, and scalene.
Types of Triangles
Here are the three main types of triangles:
- Equilateral Triangle - All sides and angles are equal.
- Isosceles Triangle - Two sides and two angles are equal.
- Scalene Triangle - All sides and angles are different.
Fun Facts!

- 🔵 The Pythagorean theorem applies specifically to right-angled triangles.
- 🔺 Triangles are used in structural engineering due to their strength and stability.
