Types Based on Sides

Understanding triangles based on sides involves examining the length and equality of a triangle’s sides. Here are the main types:

Equilateral Triangles

• All three sides are equal, and all three angles are 60 degrees.
• Symmetrical and have equal angles, making them perfect for constructing geometric figures.

Isosceles Triangles

• Two sides are of equal length, and their opposite angles are also equal.
• Commonly used in designing roofs, bridges, and artwork due to their aesthetic symmetry.

Scalene Triangles

• All three sides and angles are different.
• Versatile and can fit in irregular spaces, often used in truss designs.

Types Based on Angles

Classifying triangles by their angles focuses on the measure of the internal angles. The main types include:

Acute Triangles

• All angles are less than 90 degrees.
• Often found in designs requiring sharp and sleek contours.

Right Triangles

• One angle is exactly 90 degrees.
• Fundamental in trigonometry and used extensively in construction and engineering.

Obtuse Triangles

• One angle is greater than 90 degrees.
• Useful in creating wide, open structures and layouts.
