<span>Triangle RST was dilated by a scale factor of 1/2

Given: </span><span>triangle R'S'T', is an isosceles triangle, with each leg measuring 8 units.

Pre-image:
measure of pre-image * scale factor = measure of resulting image

measure of pre-image = measure of resulting image / scale factor

measure of pre-image = 8 / 1/2
measure of pre-image = 8 * 2/1

measure of pre-image = 16 units.</span>
