Answer 1

Answer:

If one angle of a triangle is equal to one angle of another triangle and the sides including these angles are in the same ratio (proportional), then the triangles are similar (SAS similarity criterion). The ratio of the areas of two similar triangles is equal to the square of the ratio of their corresponding sides.
