Similar Triangles

The areas of two similar triangles are 121\ c m^2 and 64\ c m^2 respectively. If the median of the first triangle is 12. 1\ c m , then the corresponding median of the other triangle is (a) 11cm (b) 8.8cm (c) 11.1cm (d) 8.1cm

If the right triangle in the figure shown are similar triangle, what is the length of the sorteer leg of the larger triangle?

The areas of two similar triangle are 81 cm^(2) and 49 cm ^(2) respectively. If the altitude of the bigger triangle is 4.5 cm, find th corresponding altitude of the smaller triangle.

The areas of two similar triangle are 100 cm ^(2) and 64 cm^(2) respectively. If a median of the smaller triangle is 5.6 cm, find th corresponding median of the other.

Triangle ABC is similar to triangle PQR. If AD and PM are corresponding medians of the two triangles, prove that : (AB)/(PQ) = (AD)/(PM)

Triangle ABC is similar to triangle PQR. If AD and PM are altitudes of the two triangles, prove that : (AB)/(PQ) = (AD)/(PM)
