Triangle

A triangle is a polygon with three sides and three angles. The sum of the angles in a triangle is always 180 degrees. There are different types of triangles based on their side lengths and angles:

• Equilateral Triangle: A triangle with all three sides of equal length and all three angles are equal (60 degrees each).
• Isosceles Triangle: A triangle with at least two sides of equal length and two equal angles.
• Scalene Triangle: A triangle with no equal sides or angles.
• Right Triangle: A triangle with one right angle (90 degrees).
• Acute Triangle: A triangle with all angles less than 90 degrees.
• Obtuse Triangle: A triangle with one angle greater than 90 degrees.

The area of a triangle can be calculated using the formula: Area = (base * height) / 2

The perimeter of a triangle is the sum of the lengths of its three sides.
