Triangles are amazing! They are important shapes in math, especially in geometry. Let’s break down the different types of triangles:

1. By Sides:

   • Equilateral: All three sides are the same length.
   • Isosceles: Two sides are the same length, and one is different.
   • Scalene: All three sides are different lengths.

2. By Angles:

   • Acute: All three angles are less than 90 degrees.
   • Right: One angle is exactly 90 degrees.
   • Obtuse: One angle is bigger than 90 degrees.

Triangles have special features. For example, the total of all their angles always adds up to 180 degrees!

Triangles are not just used in geometry. They are also found in art and engineering!
