1. A child stands before a tall building and wants to know how high it is. She notices that it is a sunny day, so armed with a meter stick, the fact that she is 1.2 meters tall, and a knowledge of similar triangles, she proceeds to measure the building’s height by comparing the length of her shadow to the length of the building’s shadow.

A. Draw a diagram that depicts the situation in the problem and label those quantities the child can directly measure herself.
