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.
Indirect Measurement: Examples
How to apply your knowledge of similar triangles and proportions to model real-life situations and to find
unknown measurements indirectly.
Example:
- A tree outside Ellie’s building casts a 125 foot shadow. At the same time of day, Ellie casts a 5.5 foot shadow. If Ellie is 4 feet 10 inches tall, how tall is the tree?
- Cameron is 5 ft tall and casts a 12 ft shadow. At the same time of day, a nearby building casts a 78 ft shadow. How tall is the building?
- The Empire State Building is 1250 ft. tall. At 3:00, Pablo stands next to the building and has an 8 ft. shadow. If he is 6 ft tall, how long is the Empire State Building’s shadow at 3:00?
