Question

Verify that llgm on the same base and between the same parallels are equal in area by paper cutting method

Answer 1

Answer:

The area of each triangle is half of the area of any parallelogram on the same base and between the same parallels. Thus, the area of the two triangles is the same. Let us formalize this as a theorem: Theorem: Two triangles on the same base and between the same parallels are equal in area.
