Unformatted text preview: 12-6 Areas of Similar Triangles
A) Theorem 12-10 a. If two triangles are similar, then the ratio of their areas is the square of the ratio of any two corresponding sides. Proof: or Examples) 1) The two triangles are similar 2) One side of two similar triangles is 8 times the corresponding side of the other triangle.
