Geometric Proportions

• The ratio of areas of two triangles is equal to the ratio of the product of their bases and corresponding heights i.e., , where, *A*_{1} and *A*_{2} are the areas of the triangles having base and height as *b*_{1}, *h*_{1} and *b*_{2}, *h*_{2} respectively.

• If two triangles have equal or common base, then the ratio of their areas is equal to the ratio of their respective heights i.e.,

• If two t…
