Abstract

This research was aimed to describing the mistakes made by the eighth grade students of SMPN 2 Tiris in Probolinggo district in solving the story problems related to the Pythagorean Theorem. Three subjects were selected to solve the story problem of the Pythagorean Theorem then interviewed. The analysis used was based on conceptual error, procedural and calculation. The results showed that in the conceptual stage the subject made a mistake in drawing a right triangle and determining the sloping side. Procedural errors are made, namely the subject makes a withdrawal of the root in the right segment even though in the left side is still a square. While at the calculation stage the subject made a mistake in determining the results of the square root and the difference so that it was wrong in the final result.
