Indirect Measurement Using Similar Triangles :
Indirect measurement is a method of using proportions to find an unknown length or distance in similar figures.
Two common ways to achieve indirect measurement involve
(1) using a mirror on the ground and
(2) using shadow lengths and find an object's height.
Method 1 measures the person's height and the distances between the person, mirror, and object.
Method 2 measures shadows and the person's height.
