a,b,c

and

u,\upsilon ,\omega

are complex numbers representing the vertices of two triangles such that

c = \left( {1 - r} \right)\;a + rb

and

\omega = \left( {1 - r} \right)u + r\upsilon ,

where

r

is a complex number, then the two triangles

View answer and explanation

Correct option: B

Are similar

Option B (Are similar) is correct because the given conditions imply that the two triangles have proportional sides and equal angles, thus they are similar.
