The ratio between the altitudes of two similar triangles is 3: 5; write the ratio between their: (i) medians. (ii) perimeters.
The ratio between the altitudes of two similar triangles is 3: 5; write the ratio between their: (i) medians. (ii) perimeters.

The ratio between the altitudes of two similar triangles is same as the ratio between their sides.

So,

(i) The ratio between the medians of two similar triangles is same as the ratio between their sides.

The ratio is

    \[=\text{ }3:\text{ }5\]

(ii) The ratio between the perimeters of two similar triangles is same as the ratio between their sides.

The ratio is

    \[=\text{ }3:\text{ }5\]
