Classification by Sides

Triangles can be classified based on the lengths of their sides as follows:

1. Equilateral Triangle:
   • All three sides are of equal length.
   • All internal angles are 60 degrees.
   • Example in real life: Roof trusses.
2. Isosceles Triangle:
   • Two sides are of equal length.
   • The angles opposite those sides are equal.
   • Example in real life: The front view of a house’s gable.
3. Scalene Triangle:
   • All sides have different lengths.
   • All angles are different.
   • Example in real life: Land plot shapes are irregular.

Classification by Angles

Triangles can also be categorized based on their internal angles:

• Acute Triangle:
  • All internal angles are less than 90 degrees.
  • Example: Triangular sails.
• Right Triangle:
  • One angle is exactly 90 degrees.
  • The side opposite the right angle is the hypotenuse.
  • Example: Ramp design in architecture.
• Obtuse Triangle:
  • One angle is greater than 90 degrees.
  • Example: Certain types of yo-yo designs.

FAQs

What makes a triangle equilateral?
– An equilateral triangle has all three sides and angles equal, each measuring 60 degrees.

Can a triangle be both right and isosceles?
– Yes, a right isosceles triangle has a 90-degree angle with two equal sides.

What is an obtuse triangle?
– An obtuse triangle has one angle greater than 90 degrees.

How can triangles be useful in design?
– They add strength and aesthetic appeal to structures and designs.

Are equilateral triangles considered regular polygons?
– Yes, because all sides and angles are equal, making it a regular polygon.
