Triangles can be classified based on different criteria, primarily by their sides and angles. Here are the main types of triangles based on these classifications:
1. **By Sides:**
– **Equilateral Triangle**: All three sides are of equal length.
– **Isosceles Triangle**: Two sides are of equal length.
– **Scalene Triangle**: All three sides have different lengths.
2. **By Angles:**
– **Acute Triangle**: All angles are less than 90 degrees.
– **Right Triangle**: One angle is exactly 90 degrees (right angle).
– **Obtuse Triangle**: One angle is greater than 90 degrees.
3. **Other Classifications:**
– **Isosceles Right Triangle**: Has a right angle (90 degrees) and two sides of equal length.
– **Equiangular Triangle**: All angles are equal, making each angle 60 degrees (also an equilateral triangle).
– **Scalene Right Triangle**: Has a right angle (90 degrees) and all sides of different lengths.
These classifications help in describing the geometric properties and relationships within triangles, which are fundamental shapes in geometry and mathematics.
