See below picture: The droplet can be divided into 2 triangles with the area of 1. They have sides of 1 and 2. Square with sides of 1 (after adding 2 matchsticks) has area of 1 so both shapes have same area of 1.
Add two matchsticks to the layout below to divide the area into two parts.The two parts must be equal in size and shape.
Add 3 matchsticks to the layout to divide it into 2 parts equal in shape and size.
Add 4 matchsticks to divide the triangle into 3 equal parts. The 3 parts may differ in shape but must be equal in size.
Can you add 6 matchsticks to divide the square into 4 pieces with EQUAL shape and ONE coin each?
Using exactly three matchsticks, can you divide the area into two equal parts?
