Using a Simple Optical Rangefinder To Teach Similar Triangles.
Cuicchi, Paul M.; Hutchison, Paul S.
Mathematics Teacher, v96 n3 p166-68 Mar 2003
Describes how the concept of similar triangles was taught using an optical method of estimating large distances as a corresponding activity. Includes the derivation of a formula to calculate one source of measurement error and is a nice exercise in the use of the properties of similar triangles. (Author/NB)
