Construction 11.2

To construct a triangle similar to a given triangle as per given scale factor.

There are two general cases

  1. Triangle to be constructed is smaller than given triangle ( Example 1 Scale factor < 1 )
  2. Triangle to be constructed is larger than given triangle ( Example 2 Scale factor > 1 )

 

Scale Factor means ratio of the sides of the triangle to be constructed with the corresponding sides of the given triangle

Scale Factor = (Side of to be constructed triangle)/(Side of given triangle)
