Applications

• Steelers Offensive Drive - This is a fun application of the Pythagorean Theorem in the context of an NFL football game.
• Steelers Offensive Drive Activity - This is a Word document to accompany the dynamic worksheet. Created by aharbaugh at the University of Pittsburgh.
  
• Ladder against the Wall, Download - application of Pythagoras' theorem, created by Markus Hohenwarter
• Cat on ladder Download Worksheet This is a problem given in one of our lectures it read "A ladder standing on a smooth floor against a wall slides down to the floor. Along what curve does a cat sitting in the middle of the ladder move" the solution of this is mainly Pythagoras' Theorem, created by David Corne
• Cat on ladder extended Download Worksheet This is an extension to this problem reading "what would happen if the cat was not on the mid-point of the ladder" also solvable using Pythagoras' Theorem and standard form of curves, Created by David Corne
