What do you understand by using the formula of hero or heroon?
Heron’s formula in geometry is a formula for finding the area of a triangle when all three sides are known. It is also called ‘Hero’s formula’. The sutra is named after Heron of Alexandria.
Formula of heron
a + b + c / 2 is called half-finite.The half-finite is denoted s.
a + b + c is called the perimeter of triangle ABC.
Where AB = c, BC = a, CA = b
Perimeter of triangle = Sum of the three sides (a + b + c)
Another method of finding the area of a triangle
Area of triangle = 1/2 × base × corresponding height.
When AC = b and BD = h where BD⊥AC then
Area of triangle = ½ × bh
What is Pythagoras theorem?
If the square of one side of a triangle is equal to the sum of the squares of the other two sides, then which is the right angle in front of the first arm.
Hypotenuse = perpendicular ² + base²
Hence, there is a right angle.
Area of right triangle = 1/2 × base × corresponding height
Area of equilateral triangle = √3 / 4 × side²
Area of the parallelogram = base × height.
Perimeter of parallelogram = 2 (sum of adjacent sides)
Area of rhombus = ½ × (product of diagonals)
Perimeter of rhombus = 4 × side
Area of a quadrilateral = ½ × (sum of vertices facing the corresponding vertices).
Area of trapezium = (sum of parallel sides) × height.
