Pythagoras' Theorem

This resource consists of a power point lesson that can be used to teach or revise the use of Pythagoras’s Theorem and 11 worksheets for consolidation or revision. The theorem is used first in right-angled triangles then in isosceles triangles and for finding the length of the diagonals of rectangles. The worksheets provide a framework for calculating the distance between two points given as co-ordinates, there are grids to help students visualise the method.  
  
Other topics covered include areas and perimeters and also the properties of triangles and a triangular prism so that Pythagoras can be applied to solving more complicated problems.
