a. triangle a

f. triangle f

Explanation:

Step1: Analyze Triangle A

Triangle A has a certain shape and size. Visually, no other triangle (B - F) has the same shape and size as A. So A is not congruent to others.

Step2: Analyze Triangle B

Triangle B's shape and size don't match any other triangle (A, C - F). So B is not congruent to others.

Step3: Analyze Triangle D

Triangle D's shape (a more "stretched" or irregular - looking triangle) doesn't match the shape of any other triangle (A, B, C, E, F). So D is not congruent to others.

Step4: Analyze Triangle F

Triangle F's shape (a different orientation and shape) doesn't match the shape of any other triangle (A, B, C, D, E). So F is not congruent to others.
(Note: Triangle C and E seem to be congruent as they have similar small, equilateral - like or isoceles - like shapes. So C and E are congruent to each other, but not to A, B, D, F.)

Answer:

A. Triangle A, B. Triangle B, D. Triangle D, F. Triangle F
