[Śulba-Sūtras] Give a method to transform a triangle into a rectangle of equal area.
Method: To transform a triangle into a rectangle of equal area:
Step 1: Take triangle ABC with base b and height h.
Step 2: Area of triangle = ½ × b × h.
Step 3: Construct rectangle with base = b and height = h/2.
Step 4: Area of rectangle = b × (h/2) = ½ × b × h = Area of triangle.
Alternative Method (by dissection): Cut the triangle at mid-height and rearrange the pieces to form a rectangle.
Explanation
The chapter discusses dissection methods from Śulba-Sūtras. A triangle can be converted to a rectangle by taking half the height and keeping the same base, or by cutting and rearranging pieces.
Solution Steps
Step 1: Take triangle ABC with base b and height h.
Step 2: Area of triangle = ½ × b × h.
Step 3: Construct rectangle with base = b and height = h/2.
Step 4: Area of rectangle = b × (h/2) = ½ × b × h = Area of triangle.
