Activities for Students: Moving a Wall: Using Geometry to Measure an Imperceptible Distance

Adam Poetzel, Matthew Hopkins, Joseph Muskin 

February 2010, Volume 103, Issue 6, Page 446

Abstract:
Students conduct a mathematical experiment to determine how far they can move a solid wall when they push against it. Intended for use in any geometry or trigonometry classroom, this lesson capitalizes on students’ prior knowledge of basic circle properties, right-triangle trigonometry, and unit conversions.
