Angles play a big role in figuring out what kind of triangle we have. Let's break it down simply:

1. Acute Triangle: All the angles are less than 90 degrees.

   • For example, an equilateral triangle, where all three angles are 60 degrees.

2. Right Triangle: One angle is exactly 90 degrees.

   • A well-known example is the 3-4-5 triangle.

3. Obtuse Triangle: One angle is bigger than 90 degrees.

   • For instance, a triangle with angles of 30 degrees, 60 degrees, and 90 degrees.

Knowing these angles is important! It helps us recognize different triangles and solve problems more easily.
