Please help me figure this out

Answer:
True
(1) You can prove two triangles are similar using AA similarity.
(2)If side length of similar figure have ration [tex]\frac{m}{n}[/tex] then the ratio of surface areas will be:[tex]\frac{m^2}{n^2}[/tex]
(3)If side length of similar figure have ratio of [tex]\frac{2}{3}[/tex] then perimeter will have ratio:[tex]\frac{2}{3}[/tex].
False:
(1)If side length of similar figure have ration [tex]\frac{m}{n}[/tex] then the ratio of Volumes will be:[tex]\frac{m^3}{n^3}[/tex]
(2)If side length of similar figure have ration [tex]\frac{m}{n}[/tex] then the ratio of surface area will be:[tex]2\frac{m}{n}[/tex]
