Answer:
Indirect Measurement
Step-by-step explanation:
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.
