Answer 2

Given :  sum of the area of three sector of the same radius are formed at the vertex of any triangle is πr ²/2​

To Find :  verify experimentally

Solution:

Use hard paper or a card board

Step 1 :  Draw a triangle

Step 2 : Using  Compass with suitable width draw arc from each vertex cutting two  adjacent sides of triangle in each case with out any intersection

Step 3 : Cut Each part

Step 4 : Arrange these parts such that they form a semicircle

As we know that area of semicircle is  π ( radius)² / 2

Hence Verified
