If an image of a triangle is congruent to the pre image what is the scale factor of the dilation_

Semantic triangle is a model proposed by C.K. Ogden and I.A. Richards in the 1920s. The functional approach assumes that the meaning of a linguistic unit can be studied only through its relation to other linguistic units and not through its relation to concept or referent
